AN/APS-143(V)
AN/APS-143(V) is an X-Band maritime surveillance and tracking radar
designed for installation in a variety of fixed-wing aircraft and
helicopters. It is known as OceanEye. The system uses a traveling
wave tube (TWT) transmitter, frequency agility and pulse compression
techniques, and consists of three units: an antenna, transceiver and
signal processor. The antenna system is pitch-and-roll compensated.
Control of the radar may be carried out by a dedicated control panel,
or by a central universal keyset via a MIL-STD-1553B databus.
Features include track-while-scan, air search mode with moving target
indication customised for the individual platform, integrated electronic
support measures interface and an integrated identification friend-orfoe system interface.
The APS-143(V)3 has small-target detection capability and is smaller
in size. This variant features a track-while-scan function and a MILSTD-1553B databus output to a central tactical navigation computer.
