AN/TPX-56 IFF Interrogator

The AN/TPX-56 IFF Interrogator set initiates the question and provides the advanced processing to determine if a target is friend or foe. The TPX-56 IFF system was developed for the U.S. Army as a state-of-the-art interrogator. This unit provides the platform with target identification, mode of operation, reply code, range, azimuth, and jamming indications. This system's capability enables the operator to maintain control of the airspace and correctly identify friendly aircraft to reduce the potential of fratricide.

Raytheon's TPX-56 IFF Interrogator is the lightest, smallest, high-performance interrogator available in the world. It can serve multiple land and sea platforms while maintaining logistics commonality. It has been selected by the U.S. Army for its Sentinel Radar and Air Traffic Navigation and Control Systems (ATNAVICS), as well as by the U.S. Marine Corps for the improved HAWK missile system.

The TPX-56 Interrogator has demonstrated its enhanced field capability and has been recognized by the U.S. Army with a "new record for correct ID" at Task Force XXI and "flawless performance" at the All Services Combat ID Exercise and Training exhibition in 1997. The TPX-56 has demonstrated its technical growth capability by integrating Mode S interrogation capability as part of the U.S. Army Advanced Concept Technology Demonstration.

The TPX-56 2500 Watt is a high-powered interrogator designed with a VME open architecture to enable maximum system flexibility and growth. The system architecture includes a 6U VME Power PC 603e processor to increase target capacity to 14,000 replies per second, target processing and platform interface. A 6U VME IFF card uses the TPX-56 patented reply decoder chipset, which incorporates leading edge pulse detection techniques. This system will support long-range/shipboard applications with enhanced receiver sensitivity of -83 dBm and long-range processing capability. This system has multiple platform interface capabilities, including MIL-STD-1553, RS-232, Ethernet and RS-422. The TPX-56 2500 Watt also is capable of being upgraded to Mode S.
