OVERVIEW: The AN/TPS-75 aka AN/TPS-43E2 is a transportable, long-range, 3-D, phased array, air surveillance, tactical radar operating in the E/F band (NATO).

DETAILS: The  TPS-75 is designed to  provide  tactical control and/or surveillance of  air operations from any location.  It is a USAF upgrade of the AN/TPS-43/70 family of radars, with significantly better electronic protection measures, increased performance, and enhanced reliability and maintainability. It is capable of simultaneously tracking up to 500 targets. It can be deployed either as a stand-alone or as remotely controlled  radar.  It can also be deployed as part of a radar network to provide an integrated air picture. 

The antenna is a flat-slotted array measuring 5.5 m x 2.54 m, consisting of 36 waveguides in array with 98 slots per waveguide. A multiple beam architecture with an entire redundant channel is employed, scanning all elevations and ranges simultaneously for targets using six beams. This ensures more hits per target for optimum clutter rejection and target extraction. The transmitted pulse is intrapulse modulated using quadrature phase-shift keying, enabling target localization within a single 6.5 microseconds long transmit pulse. 

TheTPS-75 features a Ultra-Low Sidelobe Antenna (ULSA)  antenna reducing sidelobe emissions by 50% and giving the TPS-75 an increased survivability against anti-radiation and increased jamming resistance. Other protective features include coded pulse anti-clutter detection; random or programed frequency agility; jamming analysis transmission selection; PRF stagger; precision jam strobes for triangulation; cool antenna for reduced IR signature; and instantaneous radar silence.
