The Advanced Airborne Sensor AAS is a multifunction radar installed on the Boeing P-8 Poseidon maritime patrol aircraft. The radar is built by Raytheon as a follow-on to the Littoral Surveillance Radar System LSRS, APS-149 also built by Raytheon. The AAS has its roots in the highly classified AN/APS-149 LSRS, which was designed to provide multi-function moving target detection and tracking and high resolution ground mapping at standoff ranges covering land, littoral, and water areas. The radar was deployed on a small number of P-3C Orions with "game changing" results. Containing a double-sided AESA radar with near 360-degree coverage, it could scan, map, track, and classify targets, and do it all near simultaneously; it was reportedly sensitive enough to pick up a formation of people moving over open terrain.〔(Exclusive: P-8 Poseidon Flies With Shadowy Radar System Attached ) - Foxtrotalpha.Jalopnik.com, 14 April 2014〕 Building upon the LSRS, the AAS also has a double-sided AESA radar, which contains a moving target indicator (MTI) that can detect, classify, and track targets on land and at sea at the same time, with synthetic aperture radar (SAR) and inverse synthetic aperture radar (ISAR) for picture-like radar imagery of both inland and ocean areas at the same time; these can profile vessels from a long distance and generate fine resolution without relying on optical sensors, especially in day or night and in adverse weather conditions. Once it detects and classifies a hostile vessel, the P-8 can send targeting information to another armed platform and guide a networked weapon (Tomahawk cruise missile, SLAM-ER, JASSM, LRASM, SDB II) to it through a data-link. The AAS is in ways superior to the AN/APY-7 used on the U.S. Air Force's E-8 JSTARS, looking both port and starboard rather than just being side-looking. Other potential missions could include detecting and tracking low flying and stealthy cruise missiles, communications relaying, and electronic warfare as a standoff platform to penetrate contested airspace since AESA radars are capable of radar jamming, producing fake targets, frying electronic components, and even cyber warfare.〔(Boeing P-8A Begins Advanced Airborne Sensor Testing ) - Defense-Update.com, 17 April 2014〕〔 ==See also== * Phased array * Active electronically scanned array 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Advanced Airborne Sensor」の詳細全文を読む スポンサード リンク
