1.0 SCOPE

1.1 Identification

This Specification defines the AN/TPS-59A(V)3 Radar System’s Secondary Surveillance Radar, Identification Friend or Foe (IFF) Antenna Performance requirements. The antenna is a component of the IFF subsystem and a subgroup of the Antenna Transmitter Group (ATG).

The existing Flat Plate IFF Antenna (808400/000) is a Line Replaceable Unit that is no longer manufactured and is obsolete. The Radar System has an extended service life through 2035 and requires a replacement IFF Antenna for continued support through the service life of the radar.

1.2 System Overview

The AN/TPS-59A(V)3 is a transportable, long-range, solid state, 3-Dimensional L-band radar. The AN/TPS-59A(V)3 is comprised of an ATG, Signal Data Processing Group, Power Distribution Unit, Equipment Transport Shelter, and System Cables.

The AN/TPS-59A(V)3 Radar System provides electronically scanned in elevation and continuous mechanical rotation in azimuth, automatic radar and IFF target detection and processing. The radar provides a maximum Air-Breathing Target (ABT) surveillance volume of 4 to 300 nautical miles in range, 0.5 to 19.0 degrees in elevation, 100,000 feet in altitude, and 360 degrees in azimuth.

The system performs detection of ABTs by the primary radar and detection of IFF targets by the IFF interrogator. ABT and IFF targets are correlated into a single report if they are from the same target. ABT, IFF, and correlated ABT and IFF targets are sent to the Command and Control (C2) node, as well as providing this data to the Cooperative Engagement Processor external interface in its role as a surveillance radar.

The radar may be dedicated to ABT or Tactical Ballistic Missile (TBM) target detection, classification, tracking, and reporting in a specific azimuth sector(s); or it may perform surveillance in a combined mode, which provides a balance of ABT and TBM detection and tracking within a specified azimuth sector(s). The radar provides the capability to detect, classify (as missile), and report TBM data via the C2 node for dissemination within the Marine Air Ground Task Force and to other Link 16 capable units (typically within the joint arena).

The current MARK XII IFF secondary surveillance system (AN/UPX-37, AN/UPA-61, KIT-1C, KIR-1C, KIV-77/78, etc.) is capable of interrogating Targets of Opportunity using Modes 1, 2, 3/A, C and 4. The AN/UPX-37 will be replaced by the AN/UPX-41(C) Digital Interrogator, the CP-2819 Processor and interconnecting cables. The radar is being upgraded to the MARK XIIA IFF secondary surveillance system capability for Mode 5 (Levels 1 & 2) and Mode S (Levels 1 & 2), in addition to the existing interrogation modes.

4.0 Qualification Provisions

Demonstration, Test, Analysis, Inspection, and Special Qualification Methods may be used for verification of the requirements herein. The Verification Cross Reference Matrix (VCRM) for this specification contains a mapping between the requirements herein and the test method(s) used to verify each requirement. The VCRM will be maintained as part of the program-specific requirements trace tool and is separate from this specification.

4.1 Verification Methods

Methods utilized to accomplish verification include:

Analysis (A)

An element of verification that utilizes established technical or mathematical models or simulations, algorithms, charts, graphs, circuit diagrams, or other scientific principles and procedures to provide evidence that stated requirements were met.

Demonstration (D)

An element of verification that involves the actual operation of an item to provide evidence that the required functions were accomplished under specific scenarios. The item may be instrumented and performance monitored.

Inspection (I)

An element of verification that is generally nondestructive and typically includes the use of sight, hearing, smell, touch, and taste; simple physical manipulation; and mechanical and electrical gauging and measurement.

Test (T) An element of verification in which scientific principles and procedures are applied to determine the properties or functional capabilities of items.

4.2 Production Qualification Test (PQT)

The PQT shall verify all of the technical specification requirements listed in this performance specification through a series of verification tests, demonstrations, inspections and analyses.

PQT antenna system verifications are shown in the IFF Antenna Replacement Verification Cross Reference Matrix (VCRM). The VCRM is separate from this specification.

4.3 VCRM

The verification method(s) for the PQT shall be as outlined in Table 4-2, VCRM. When more than one verification method is specified in the VCRM (such as: A/D), the most rigorous method identifies the preferred verification method. The second position identifies the alternate method that may be used provided the Vendor can prove the requirement was met previously through a Government observed test or approved similarity analysis. The Government reserves the right to make the determination.

The contractor may submit past test data or vendor data as a means of showing compliance to selected requirements of this specification, as long as the approach is documented in the Test Plan and approved by the Government.

This test data shall be included as part of the Test Plan. The Test Plan approach shall include information such as the identification of the requirement the data is trying to satisfy, the Test Procedure utilized, the data/results obtained, documentation of the unit under test (i.e., confirm that the unit under test is the final design product intended for the antenna system) and an analysis of the results to verify compliance to the appropriate specification requirement. Acceptance of any such past data or analysis to satisfy specification requirements in lieu of testing shall be at the Government's discretion.

Rejection by the Government of the test data, vendor data, the proposed approach or contractor data analysis shall require the contractor to perform a test to show compliance to the technical specification requirement that was not satisfactorily addressed by data/data analysis.

5.0 Requirements Traceability

The Requirements Traceability Matrix (RTM), contains a mapping of the engineering requirements in this specification to the applicable requirements in the lower-level specifications for the system. The RTM will be maintained as part of the program-specific requirements trace tool and is separate from this specification.

6.0 NOTES

6.1 Definitions

Antenna Transmitter Group The Antenna Transmitter Group is responsible for transmission and reception of RF energy to cover the system’s surveillance and track volumes, and consists of the trailers (used for both transport and emplacement), the transmit / receive primary and secondary antennas, and supporting equipment.

Electronics Group The Electronics Group consists of the hardware and software that processes data from the Antenna Transmitter Group, supports operator control of the system, and supports the system’s external interfaces, as well as the shelter enclosing this hardware.

Corrective Maintenance Corrective maintenance is the action required to restore equipment which has failed.

Mean Time Between Critical Failure The time between failures that result in the radar not meeting any critical performance requirement. MTBCF excludes those portions of the radar (e.g., service lift) that are not required for tactical operation Mean Time-to-Repair MTTR includes all repair time and downtime associated with the failure of the system except for the logistics of spare parts. MTTR is exclusive of Government Furnished Equipment (GFE).

Scheduled or Preventive Maintenance Scheduled or preventive maintenance is systematic action deemed necessary to reduce or eliminate failures, prolong operating time, and prolong the useful life of the equipment. Periods of scheduled maintenance resulting in system down time are not used in determining Availability, MTBCF, or MTTR.
