Appendix A - Report to Congress on the Weather Radar Follow-On Plan: Research and Risk Reduction to Inform Acquisition Decisions Appendix B - NOAA Readiness Levels

1. INTRODUCTION

The Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), Office of Oceanic and Atmospheric Research (OAR), National Severe Storms Laboratory (NSSL) has a need for a Phased Array Radar (PAR) test article (aka Radar Test Article). NSSL will conduct risk reduction activities that will support the National Weather Service (NWS) Analysis of Alternatives (AoA) for the next operational radar system, as indicated in the Report to Congress on the Weather Radar Follow-On Plan: Research and Risk Reduction to Inform Acquisition Decisions (Appendix A). This report highlights the need for further development of PAR technology, if it is to be considered as a long-term option for the next phase of NWS operational radar system. NOAA, OAR, NSSL will conduct risk reduction activities on an acquired PAR test article to investigate the feasibility and capability of a dual linear polarized, S-band, PAR system that can:

● Serve as a proof-of-concept of a single face rotating PAR weather surveillance radar;

● Provide rapid volume update times (1.5 mins - 2 mins) through a combination of electronic and mechanical scanning rather than traditional mechanically rotating parabolic antennas; and

● Provide a scanning capability allowing multiple simultaneous beams to test various advanced operational modes (scanning methods) and assess data quality tradeoffs.

The technical knowledge learned from the test article risk reduction research and development (R&D) will be shared with the NWS to support their AoA for the next operational weather radar system.

2. BACKGROUND

NOAA, OAR, NSSL has been investigating PAR technology since 2003 to meet mission-driven expanded radar requirements that support improved and enhanced weather warnings. PAR is a promising technology that has demonstrated great potential to improve warnings for various types of severe weather, primarily through the use of faster updates and adaptive scanning capabilities. However, there are many technological challenges that must be addressed before PAR technology can serve as a replacement for the current weather radar fleet consisting of the Weather Surveillance Radar – 1988 Doppler (WSR-88D) radars. Chief among these technological challenges is the inclusion of dual polarization within the PAR technology.

To address these challenges, NOAA, in partnership with the Federal Aviation Administration (FAA), developed the Advanced Technology Demonstrator (ATD), which is the first dual-polarization, S-band PAR developed specifically for weather applications. The ATD is a first-of-its-kind test system that was installed at NOAA’s NSSL in Norman, Oklahoma in 2018. Its primary objectives are to evaluate the calibration and performance of dual polarization on PAR technology and to demonstrate advanced scanning techniques for weather radars using PAR. The ATD achieved initial operating capability (IOC) in 2021 and is currently being used to conduct experiments. Development of the ATD has moved PAR technology to a NOAA Readiness Level (RL) 5 for dual polarization meteorological applications (Appendix B). Further research and development is needed before NOAA can make a decision regarding PAR technology as an appropriate replacement for the WSR-88D radar system.

In much of the work outlined above, NOAA was engaged with other government agencies exploring a stationary, multi-face planar array or cylindrical array to satisfy weather surveillance requirements as well as aircraft surveillance. The multi-agency requirements for disparate update rates precluded a rotating planar array architecture.

However, a multi-agency solution is no longer being considered, and NOAA is now pursuing the procurement of a rotating planar PAR system for weather surveillance only. To be advantageous over conventional weather radars, a rotating planar array would need to incorporate some advanced technologies with multiple simultaneous beams to achieve the desired rapid volume updates for weather surveillance.

NOAA NWS’ Radar Operations Center (ROC) is engaged in a Service Life Extension Program (SLEP) to extend the operational capability of the WSR-88D system until approximately 2035. Ongoing information technology refresh and sustaining engineering programs will support the continued operation of the WSR-88D network through approximately 2040. NOAA anticipates making a key decision in 2028 whether to continue to maintain the current system or to replace it. NOAA has developed a research plan to enable the technological progress needed to prepare for a formal AoA beginning in 2028 to include cost-benefit analysis of:

1) Sustaining the current system through an additional SLEP;

2) Replacing WSR-88D with a new reflector dish, mechanically rotating radar system; or

3) Replacing WSR-88D with the PAR technology.

Considering the many benefits for operation already demonstrated by PAR technology, NOAA is exploring a next-generation PAR as an option to replace the WSR-88D network. Critical to NOAA is whether the technology can be matured in time to serve its need. This acquisition–and the subsequent years of research using it–will fill in a key gap in NWS’ AoA to help NOAA make an informed decision.

3. SCOPE

The Contractor shall furnish all necessary personnel, equipment, materials, supplies, and services, except as otherwise specified, to provide and install a turn-key PAR system in central Oklahoma. Scope to include construction of the radar tower, support infrastructure, training, and operational and maintenance support post installation. Real estate is not included in the scope.

4. OBJECTIVES

NOAA will acquire an azimuthally rotating, single-faced planar, dual-polarized, S-band PAR for the purpose of conducting research on the types of advanced scan strategies this architecture would enable. These scan strategies involve multiple simultaneous beams, requiring an active electronically-scanned array with a high degree of digitization. The PAR shall be an S-band radar with a broadside circular beamwidth of less than or equal to 1.75° (with a beamwidth of <1.5° preferred). The PAR shall be elevated from the surrounding ground level such that the base of the antenna is positioned at a height of approximately 15 m [height will be finalized upon site selection]. To be of benefit within NOAA’s timeline, the system shall be delivered and functional within 24 months of the award.

5. TECHNICAL TASKS AND REQUIREMENTS

This PWS is organized into five (5) tasks: radar test article, construction of the radar facility, installation of the radar test article, training and documentation, and support/maintenance.

5.1. TASK 1: RADAR TEST ARTICLE (RTA)

Task 1 is the development and delivery of a Radar Test Article (RTA). The RTA is defined as the rotating PAR antenna, along with any associated electronics, computer servers, radio frequency (RF) equipment, mechanical equipment, cooling equipment, etc. to compose a complete functional radar system. (Note: There is some understood overlap between Task 1 and Task 2. For example, the rotating mechanism may be conceptually better included in the RTF or RTA, depending on the design. The important thing is not the breakdown of Task 1 and Task 2, but that all functional requirements are covered by the proposal.)

RTA requirements:

5.1.1. The Contractor shall deliver a RTA.

5.1.2. The RTA shall include an active electronically scanned array (AESA) capable of scanning ±45° off broadside in elevation and azimuth (independently) without grating lobes. It shall also be capable of scanning within the entire range of ±45° azimuth and 0-20° elevation (simultaneous azimuth and elevation scanning) without grating lobes.

5.1.3. The RTA shall be capable of mechanical azimuthal rotation, with a configurable rate from 0° per second to at least 25° per second.

5.1.4. The RTA shall allow continuous azimuthal rotation in either direction (clockwise or counterclockwise) through the full 360° (i.e. not tethered).

5.1.5. The RTA shall be designed to operate in the frequency range of the S-band (2.7-3.1 gigahertz GHz).

5.1.6. The RTA shall be capable of dual-linear (horizontal and vertical) polarization with a minimum of the two (2) following modes of operation:

● Simultaneous transmission of horizontal and vertical polarizations; and,

● Alternating transmission of horizontal and vertical polarizations.

The RTA shall be capable of simultaneous receive of horizontal and vertical polarizations for both simultaneous and alternating transmission modes.

5.1.7. The RTA shall have a sensitivity of >11.0 decibels (dB) Signal to Noise Ratio (SNR) for a 1 meters squared (m2) target at 100 kilometers (km) when steered electronically within ±45° azimuth, 0-20° elevation (equivalent minimum detectable signal of <10.0 decibels of Z (dBZ) at 100 km with 0.0 dB SNR).

● This sensitivity requirement is specified for conventional, single-beam operation and shall be simultaneously met with range resolution and antenna pattern requirements for this mode. It is understood that possible user-defined configurations (e.g. short pulse width, low duty cycle) and modes of operations described in this PWS (e.g. spoiled transmit, multiple simultaneous transmit) will reduce the sensitivity with respect to conventional single-beam operation.

5.1.8. The RTA antenna shall meet or exceed the following antenna pattern characteristics, for the entire range of

3.0 - 3.1 GHz:

● Beamwidth: ≤ 1.75° at broadside, with a preferred beamwidth of ≤ 1.50°. This refers to the one-way equivalent1 circular beamwidth, which can be expressed as follows given a transmit (Tx) beamwidth 𝜃𝜃𝑡𝑡 and receive (Rx) beamwidth 𝜃𝜃𝑟𝑟:

𝜃𝜃𝑒𝑒 = √2𝜃𝜃𝑡𝑡𝜃𝜃𝑟𝑟 �𝜃𝜃𝑡𝑡2 + 𝜃𝜃𝑟𝑟2

Note: for the purpose of this requirement, only the intrinsic beamwidth of the antenna, including any tapering applied in operational conditions, should be considered. Unweighted patterns exceeding sidelobe specifications or signal processing techniques to recover resolution do not suffice for the purpose of this requirement;

● Receive Sidelobes (one-way): first sidelobe ≤ -25 dB off peak, Mean Squared Sidelobe Level (MSSL) ≤ -50 dB off peak;

● Cross-pol isolation (on transmit): > 40.0 dB at broadside for Tx; and,

● Cross-pol isolation (on receive): > 35.0 dB at broadside for Rx.

5.1.9. The RTA shall have a range resolution of <250 m.

5.1.10. The RTA shall include a means to calibrate:

● Absolute range offset: a scalar to establish a relation between received echo timing and absolute range (km);

● Absolute reflectivity offset: a scalar to establish a relationship between received echo power and absolute reflectivity (dBZ);

● Broadside differential reflectivity (ZDR) bias: a scalar to correct for the difference in power between horizontal and vertical beams at broadside;

● Scan loss: a correction for the change in gain as function of steering angle; and,

● Horizontal (H)/ Vertical (V) beam peak offset: a correction for any mismatches between H and V beam peaks (both amplitude and pointing angle) as function of steering angle

5.1.11. The RTA antenna shall be all-digital or highly digital on receive, with highly digital defined as no more than

16 receive elements per digital channel.

5.1.12. The RTA shall be capable of operating in the following modes:

● Electronic scanning while stationary;

● Electronic scanning while mechanically rotating 360° in azimuth;

● Support single-beam operation.

● Support spoiling (intentional broadening) of the transmit beam and packing of multiple simultaneous narrower receive beams within the transmit beam geometry. The RTA shall support spoiling/packing in both azimuth and elevation, with a minimum of three (3) simultaneous receive beams;

● Support multiple simultaneous transmit pulses in different directions followed by simultaneous receive (sometimes referred to as “shotgun” mode in literature), with a minimum of three (3) transmit/receive beams; and,

● Support multiple concatenated transmit pulses in different directions followed by simultaneous receive (sometimes referred to as “machine gun” mode in literature), with a minimum of three (3)

1 Conventionally, beamwidth is understood to be the 3 dB width of a one-way antenna pattern based on the assumption of transmit/receive reciprocity. In the case of a PAR antenna, the transmit and receive patterns may not be reciprocal due to techniques employed such as thinned transmit arrays and tapering. Therefore, the conventional definition is ambiguous, and it is useful to define an unambiguous “one-way equivalent” to keep language consistent across antenna architectures. The one-way equivalent may be thought of as the one-way pattern of a hypothetical reciprocal antenna yielding the same two-way pattern as the PAR’s non-reciprocal transmit/receive combination.

transmit/receive beams. Concatenated transmit pulses at the same center frequency and different center frequencies (to improve the ability to distinguish on receive) shall be supported.

o Without blind range mitigation, multiple concatenated transmit pulses will have an adverse impact on the blind range. For demonstration of this mode, the blind range for three (3) pulses without blind range mitigation should not exceed 20 km. Blind range mitigation may be employed to more easily meet the sensitivity specifications.

5.1.13. The RTA shall support arbitrary user-defined waveforms from 0.5 to 150 microsecond (µs).

5.1.14. The RTA shall support pulse compression.

5.1.15. The RTA shall support pulse-to-pulse phase coding. That is, it shall support an arbitrary user-specified phase on a pulse-to-pulse basis and per polarization (horizontal and vertical).

5.1.16. The RTA shall support duty cycle up to at least 8 percent simultaneous dual-linear or 16 percent single polarization.

5.1.17. The RTA shall provide a real-time display of spectral moments (reflectivity, velocity, spectrum width) and dual-polarization variables (differential reflectivity, differential phase, specific differential phase, correlation coefficient).

5.1.18. The RTA shall allow recording of weather spectral moments and dual-polarization variables.

5.1.19. The RTA shall allow recording of beamformed I/Q data (i.e., the amplitude of the in-phase (I) and quadrature

(Q) signals) for each polarization channel.

● Data storage for a minimum of eight (8) hours continuous duration.

5.1.20. The RTA shall have a well-documented external interface or Application Programming Interface (API) for integration of customer command and control, signal processing, product generation, and visualization software.

5.1.21. The RTA shall be operable in instantaneous rain rates of at least 300 millimeters per hour (mm/hr) and hourly accumulations of at least 100 millimeters (mm) without damage to equipment.

● The effect of water on the radome should be taken into consideration during system design.

Electronic scanning within a wet (i.e., reflective) spherical radome can create localized areas of excessive electric field magnitude due to coherent summing (spatial focusing) of reflections. The RTA antenna must be resilient to localized reflections from water on the radome, including (but not limited to) preventing damage to Tx/Rx elements.

5.1.22. Array cooling shall be sufficient to allow operation of the radar without overheating or losing calibration (e.g., ceasing to meet sensitivity, beamwidth, or sidelobe requirements due to temperature or thermal gradients across the array) in outdoor temperatures between -30°C and +45°C.

5.1.23. The RTA shall provide active monitoring of critical system status andThe RTA shall have a minimum 10 percent sparing model of any known high failure rate items.

5.1.24. The RTA antenna face shall have a mechanical elevation angle between 0.0° and +3.0° if fixed. An adjustable mechanical elevation angle (i.e., a means to change the mechanical tilt) from 0.0° to +3.0° or greater is preferred. The intent of this preferred requirement is to evaluate rotating PAR performance at various fixed elevation angles.
