AN/APS-80

AN/APS-80 is operating in the X-band maritime airborne surveillance and surface search radar using two mechanically scanned antennas to provide 360° coverage, with one antenna in the nose, the other in the tail. The radar uses the indicator group AN/APA-125, but it is not part of the radar. AN/APS-80 was installed on the US Navy’s P-3C Orion long-range maritime patrol (LRMP) aircraft, to replace the AN/APS-20.

The original AN/APS-80 produced a single 2.6 × 3.4° beam, but later version, AN/APS-80A produces two beams: a 3.6° pencil beam and an 18° fan beam.

AN/APS-88

AN/APS-88 is a light weight derivative of AN/APS-80 with more compact size for smaller aircraft such as Grumman S-2 Tracker and Grumman HU-16 Albatross. The peak power is 45 kW. The maximum range is, therefore, reduced to 35 NM (≙ 65 km).
