1 SCOPE

This document details the requirements for an Airspace Non-Cooperative Surveillance Radar (ANSR). The scope of the ANSR Program is to procure and deploy a modern commercial off-the-shelf (COTS) Non-Cooperative Surveillance Radar System that operates in the Terminal Airspace within the National Airspace System (NAS). Identifying alternative technologies will address the shortfall of exceeded service life of the currently operating ASR-8, ASR-9, and ASR-11 systems while continuing non-cooperative radar surveillance services, enhancing these services, and adding new functionality to meet the current needs of the NAS. A full system replacement provides an opportunity to explore alternative technologies such as advanced (non-rotating) antennas, improve functionality and capabilities to support FAA requirements, consolidate Terminal Non-Cooperative Surveillance Radar Systems into a single baseline and simplify maintenance through a significant reduction in the number of Line-replaceable Units (LRUs) in the system.

1.1 Introduction

The FAA operates and maintains several surveillance radar types in the terminal environment which is generally defined as zero to 60 nautical miles (nm) from the airport reference point, from the surface to 24,000 feet (ft) in elevation. Primary (non-cooperative) aircraft surveillance from these radars, the Airport Surveillance Radar (ASR) models 8, 9 and 11, is based on reflections from an airframe and does not require any equipment on-board the aircraft. Conversely, Cooperative Surveillance Radars (CSR) interrogate transponder equipped aircraft through an antenna, mounted above the primary radar’s sail antenna to obtain International Civil Aviation Organization (ICAO) address, aircraft identification (Mode 3/A), and Aircraft Altitude (Mode C) information from the transponder to generate beacon target reports. The surveillance data, including aircraft range and azimuth, generated by the ASRs are used to reinforce beacon target reports generated by the collocated CSR. The final output of the radar system includes reinforced target reports, Secondary Surveillance Radar (SSR) only Target Reports and Primary Surveillance Radar (PSR) only target reports that are delivered to FAA automation systems.

The FAA currently operates independent baselines of non-cooperative surveillance radars in the terminal domain and these systems are reaching, or have already reached, the end of their service life and require technology upgrades or replacement by 2035. The Airport Surveillance Radar – Model 8 (ASR-8) was first deployed in 1975, ASR-9 in 1985 and ASR-11 in 2003 as illustrated in Figure 1-1.

FAA-E-XXXX, Rev. DRAFT, August 30, 2024 Page 2 of 43

Figure 1-1 – Legacy ASR Deployment Year

The ASRs include aging technology and were not designed to address modern data communications or cybersecurity requirements nor changes to the NAS such as the emergence of wind turbine clutter. Additionally, many spare parts are no longer available for purchase, repair or redesign and these logistical difficulties affect each system. In some cases, spare parts are taken from cannibalized systems or, if spare parts are unavailable, radars must operate in single channel mode for extended periods of time. The ongoing support strategy has been to replace individual subcomponents through technical refresh or sustainment programs. Those radar sustainment programs are now encompassed under a Terminal and En Route Surveillance Tech Refresh Portfolio (TES TRP). The Airspace Non-Cooperative Surveillance Radar (ANSR) Program, contained in the NAS Enterprise Architecture Surveillance Infrastructure Roadmap, was initiated to provide a non-cooperative surveillance system that will replace the legacy ASRs that are currently in the NAS. The ANSR Program will ensure the sustainment of non-cooperative surveillance services in the NAS and add necessary functionality to enable the following operational improvements:

• Right-size the NAS surveillance infrastructure by optimizing radar coverage

• Mitigate false targets caused by windfarm clutter and improve aircraft detection in surrounding areas

• Improve aircraft detection through modern architecture and algorithms

• Solve Time Division Multiplexing to Internet Protocol (TDM-to-IP) associated with non-cooperative radars

• Provide a modern system that complies with current FAA security standards and mitigates cyber security threats

There are certain airspaces where aircraft are not required to be transponder equipped and some aircraft (for example, recreational aircraft) have waivers eliminating the transponder requirement

FAA-E-XXXX, Rev. DRAFT, August 30, 2024 Page 3 of 43 regardless of airspace type. Further, transponder equipped aircraft may fail to be detected due to the loss of ADS‐B during a Global Positioning System (GPS) interference, spoofing or jamming event, failure of the transponder or certain bad actors that may disable a functioning transponder in order to avoid being detected all together. This lack of transponder equipped aircraft means primary radars are required to fill this gap in surveillance coverage as well as mitigate potential safety hazards of aircraft not being seen by Air Traffic Controllers. Without a sustainable primary radar system, the long-term future of primary radar poses high risks to aviation safety and national security.

The aim of the Terminal Precipitation on the Glass (TPOG) Program is to provide precipitation weather data for most if not all Terminal Radar Approach Control (TRACON) facilities. The ANSR program includes precipitation weather requirement until TPOG is fielded and demonstrated. The ANSR Program will continue to monitor the TPOG Program and evaluate the need for precipitation weather requirements throughout the investment analysis phase. The Weather Systems Processor (WSP) functionality is not part of the ANSR Program scope.

1.2 Description

Between 1975 and 2005, the FAA procured three Non-Cooperative Surveillance Radar systems that have already reached, or will reach, the end of their service life and will need technology upgrades or replacement by 2035. Additionally, there are shortfalls in system performance described below that must be addressed to continue existing non-cooperative services in the NAS.

Unfortunately, although sustainment programs, such as TES TRP, can be an effective way to maintain an existing radar network, they are not the best means to introduce modern technology, to improve surveillance and meet emerging requirements. Reliance on sustainment programs can often lead to the use of obsolete technology, continuation of inefficient support processes, increased costs, and delays in the replacement of an aging infrastructure. These factors can lead to significant increases in lifecycle cost, increased safety risks due to system outages, and lengthening mean time to repair as supply chain and labor support for repairing these systems continue to dwindle.

The NAS operational environment will remain the same for ANSR and meet the same interoperability requirements for FAA ATC Automation Systems with both aircraft and weather data as with legacy terminal ASRs. However, ANSR will address legacy Terminal ASR baselines that are at the end of their service life and need technology upgrades or replacement by 2035. ANSR will also increase operational availability and decrease performance deterioration resulting from declining availability of replacement parts due to obsolescence.

Figure 1-2 shows the high-level context diagram for ANSR. The ANSR system consists of three subsystems:

1. The Transmitter subsystem

2. The Receiver subsystem, and

3. The Radar Processing subsystem.

Figure 1-2 – ANSR Context Diagram

ANSR will address modern data communications requirements, cybersecurity requirements and changes to the NAS such as the emergence of wind turbine clutter that were not present when the legacy ASRs were procured. ANSR will address the technology upgrades to address all of the shortfalls that are needed on the legacy ASRs and provide a non-cooperative surveillance capability to the NAS for the next 20+ years.

FAA-E-XXXX, Rev. DRAFT, August 30, 2024 Page 5 of 43

1.3 Constraints

The following constraints are associated with the procurement of a new system:

1. ANSR is not required to detect or track small radar cross section aircraft such as UAS.

2. Upgrades to current infrastructure such as power, ventilation, air conditioning, and communications may be needed for ANSR.

3. Procurement of a new system requires a significant financial and time commitment for implementation.

5. The performance requirements for ANSR will be inherited from the documented requirements of the legacy systems.

6. ANSR will be fully compatible with all aspects of the NAS and will not interfere with or cause degradation to the NAS.

7. ANSR will result in no negative impacts and no additional requirements for NAS systems relying on its data.

The implementation of the ANSR will require coordination among the radar sites scheduled to receive new equipment and the various automation sites they feed.

To minimize interruptions in service to the greatest extent practicable during installation and Site Acceptance Testing (SAT), the ANSR and the legacy ASR systems will need to run alternately with a switch for the active interrogator. Additional temporary space at the radar sites to accommodate both systems, as well as a method to quickly swap connections to the existing antenna system and automation feeds, will be provided.
