The AN/APG-66 radar is an X-band solid state medium range (up to 80 nmi) pulse-Doppler planar array radar originally designed by the Westinghouse Electric Corporation (now Northrop Grumman) for use in early generations of the F-16 Fighting Falcon. Later F-16 variants use the AN/APG-68 or the AN/APG-83. This radar was employed in all domestic and export versions of the F-16A/B models throughout the production. Subsequent upgrades have been installed in many varying aircraft types including the U.S. Customs and Border Protection's C-550 Cessna Citation, US Navy P-3 Orion, and Piper PA-42 Cheyenne II's.

Capabilities

Developed from Westinghouse's WX-200 concept radar, the AN/APG-66 was designed for operation with the AIM-7 Sparrow, AIM-120 AMRAAM, and AIM-9 Sidewinder missiles. Production of system components also involved Belgium, Denmark, Netherlands and Norway. The system has 10 operating modes for air-to-air (search and targeting) and air-to-surface operation. Air-to-ground offers ground mapping, doppler beam-sharpening, beacon, and sea modes. It has both "uplook" and "downlook" scanning capabilities. In uplook mode, the radar uses a low Pulse-Repetition Frequency (PRF) for medium- and high-altitude target detection in low clutter, while downlook mode uses medium PRF for target detection in heavy clutter environments. In operation, it also has jamming resistant frequency agility.

Composition

The radar system is composed of six individual line-replaceable units (LRUs). They consist of:
