AN/APS-133
AN/APS-133 (Manufacturer’s designation: RDR-1FB) was operating in X-Band multimode, digital colour display radar. It is derived from the commercial RDR-1F equipment and was designed to provide military aircraft with weather avoidance, terrain-mapping and beacon homing facilities. The APS-133 consists of four or five units: transceiver, colour display unit, control panel, and a fully stabilised antenna. The display may also be used in conjunction with an optional auxiliary interface.
