AN/APY-10 – Wikipedia

american multifunction radar
The AN/APY-10 is an american multifunction radar developed for the U.S. Navy ‘s Boeing P-8 Poseidon nautical patrol and surveillance aircraft. [ 1 ] AN/APY-10 is the latest descendant of a radar kin primitively developed by Texas Instruments, and now Raytheon after it acquired the radar business of TI, for Lockheed P-3 Orion, the harbinger of P-8. The AN/APY-10 mechanically scanned radar is a exploitation of Raytheon ‘s AN/APS-149 radar. [ 2 ] Compared to the AN/APS-137, it is smaller in size, lighter, and uses less ability. [ 1 ] The radar is optimized for nautical, littoral and overland surveillance. [ 3 ] The AN/APY-10 is able to provide high resolution radar images in both overland and water modes. available modes include color upwind, synthetic aperture radar ( SAR ), inverse synthetic aperture radar ( ISAR ), periscope detection, and navigation. ISAR mode is said to be able of both detection, imaging and classifying coat targets at long crop using a variety of resolutions. [ 1 ]

The AN/APS-80 is the first penis of the radar syndicate the AN/APY-10 directly descends from, and this first penis of the syndicate was installed on P-3A/B. AN/APS-80 is an analogue radar with a peak exponent of 143 kilowatt. The original AN/APS-80 produced a individual 2.6 ten 3.4 degree glow, but late translation, AN/APS-80A produces two beams : a 3.6 degree pencil air and an 18 degree fan beam. A singular feature pioneered by AN/APS-80 is that it adopts two antennas to provide 360 degrees coverage, with one antenna in the nose, the other in the tail, under the magnetic anomaly detector ( MAD ). The size of the antenna is 42 inches for AN/APS-80, 42 adam 24 inches for AN/APS-80A, and the gain is 34 decibel for AN/APS-80 and 35 dubnium for AN/APS-80A. Each antenna can cover a 210-degree sector, and the scan rate for AN/APS-80 is either 6 or 12 revolution per minute ( revolutions per minute ), covering the scan sector of 36 or 72 degrees per second. For AN/APS-80A, the scan rate is 6 revolutions per minute at 45 degrees per second or 48 scans per hour. [ 4 ]
AN/APS-88 is a lighter weight derivative of earlier AN/APS-80 with more compact size for smaller aircraft such as Grumman S-2 Tracker. The top out might is 45 kilowatt and like AN/APS-80, AN/APS-88 is besides an X-band radar. [ 4 ]
AN/APS-115 is a exploitation of AN/APS-80A, [ 4 ] and it is the beginning try of digitization by providing digital input into the digital battle system installed on the P-3. early improvement over the original AN/APS-80 included the integration of two separate AN/APS-80A radar into a single unit via a unmarried planar position indicator ( PPI ) display. The most important improvement is that AN/APS-115 is an automatic pistol version of earlier AN/APS-80/80A, but some users felt that in the hands of an know operator, the manual analogue AN/APS-80/80A has a better luck to detect modest targets such as submarine periscope in sea clutter. AN/APS-115 utilize cavity magnetron .
X-band AN/APS-116 is the upgrade AN/APS-88 using technologies and experience gained in the achiever of AN/APS-115. The biggest deviation between AN/APS-115 and AN/APS-116 is that while the early has two antennas like AN/APS-80, the latter lone has a one antenna in the nose of the platform like AN/APS-88 it replaced. AN/APS-115 is able to achieve a resolution of 1.5 foot and the typical range against a submarine periscope is 15.5 nautical miles ( nanometer ). [ 4 ]

Knowledge gained in the growth of AN/APS-115/116 is used in the development of X-band AN/APS-124, the first gear model in the radar class developed for ASW helicopters. Due to the borrowing of the traveling roll tube ( TWT ), the point ability is importantly increased to 350 kilowatt. Due to the size and weight restraint, the parabolic antenna of radars for fixed aircraft is replaced by a 183 adam 30.5 curium ( 72 column inch adam 12 column inch ) slotted planar array antenna for AN/APS-124, and scan pace is 6 or 12 rpm, with 120 revolutions per minute for weather. The array of AN/APS-124 produces a 1.2 ten 20 degrees beam, and the typical range against a 1 square meter target is 16 new mexico in comparison to 20 nm of AN/APS-115/116. AN/APS-124 is installed on Sikorsky SH-60 Seahawk. [ 4 ]
AN/APS-127 is a derivative of AN/APS-124 adopted for light fixed wings aircraft. AN/APS-115/116 was excessively heavy and bulky for light aircraft, and AN/APS-124 for helicopters was an ideal candidate for adoption for light fixed winged aircraft, and the result is the X-band AN/APS-127, which equipped Danish Gulfstream III and USCG HU-25. [ 4 ]
Knowledge gained from the success of AN/APS-124 and AN/APS-127 was used to upgrade AN/APS-115 and AN/APS-116, and the consequence is the X-band AN/APS-134, which has a track while scan ( TWS ) mode, and up to 32 surface targets can be simultaneously tracked. Developed as an “ international successor ” to AN/APS-115/116, AN/APS-134 utilizes TWT and it is integrated with on board electronic war confirm measures ( ESM ). [ 4 ]
A far development of AN/APS-115/116/124/127/134 is the X-band AN/APS-137, incorporating man-made aperture radar ( SAR ), inverse synthetic aperture radar ( ISAR ) and Ground moving target indication ( GMTI ) modes. The resolution in SAR & ISAR modes is 0.9 molarity ( 3 foot ). A helicopter version of AN/APS-137 was besides developed, but it lost out to Telephonics AN/APS-143. [ 4 ]

AN/APS-148 Sea Vue ( SeaVue ) radar is a X-band radar based on the cognition of AN/APS-137, developed by Raytheon for light fixed winged aircraft. SeaVue is a modular blueprint that is upgradable, with only three line-replaceable units. [ 4 ]
AN/APS-149 Littoral Surveillance Radar System ( LSRS ) is the first mannequin in the radar family that adopts active electronically scanned array ( AESA ) radar, and it is developed for littoral and overland surveillance radar, initially fielded aboard the military service ‘s P-3C Block Modification Update Program ( BMUP ) maritime patrol and surveillance aircraft. The wide-aperture radar is mounted in a ventral pod attached to the belly of the master of ceremonies aircraft by at least three fastening points. [ 5 ] [ 6 ]
AN/APS-506 is the canadian derivative of AN/APS-116 with the addition of Spotlight SAR mode. Two more extra real-time visualize modes are besides incorporated, including ISAR and strip map modes. [ 4 ]
