AN/APG-73
The AN/APG-73 is an X-band multimode fire-control airborne radar developed by Hughes Aircraft Company Radar Systems in the 1980s. Operational since 1992, it has been deployed on US Navy and Marine Corps F/A-18C, D, E, and F aircraft, as well as in the air forces of Finland, Switzerland, Malaysia, Australia, and Canada. Manufactured by Raytheon, the last unit was delivered in June 2006. This all-digital, all-weather, coherent, multimode, multi-waveform search-and-track sensor is based on the AN/APG-65 design, incorporating technology from the APG-70 and APG-71 radars. While retaining the AN/APG-65's antenna and traveling wave tube (TWT) transmitter, the AN/APG-73 features a new data processor, power supply, and receiver/exciter, providing increased memory, bandwidth, frequency agility, and higher analog/digital sampling rates. These upgrades enhance electronic counter-countermeasures through flexible software, improve radar resolution cell and Doppler resolution via faster analog-to-digital conversion and a new signal processor, enabling better discrimination of closely-spaced targets. The system was later replaced by the AN/APG-79.
