SeaVue XMC

SeaVue is a X-Band radar based on the Raytheon AN/APS-137 for light fixed winged aircraft. SeaVue is a modular design that is upgradable, with three line-replaceable units. The AN/APS-137(V5) was renamed to AN/APY-10 later.

The SeaVue XMC (eXpanded Mission Capability) maritime surveillance radar's innovative features provide both radar and mission system advanced capabilities, such as automatically detecting, tracking and sorting thousands of maritime targets simultaneously and correlating radar tracks with Automatic Identification System (AIS) contacts. The system also geographically registers radar detections to AIS data and digital nautical chart features, allowing for more precise target tracking, locating of threats and accurate cross-sensor cueing to the electro-optic system.

When a radar operates in the ISAR mode, its antenna no longer scans, but constantly illuminates the target in a searchlight mode.
