The AN/APY-10 is an American multifunction radar developed for the U.S. Navy's Boeing P-8 Poseidon maritime patrol and surveillance aircraft.[1] AN/APY-10 is the latest descendant of a radar family originally developed by Texas Instruments, and now Raytheon after it acquired the radar business of TI, for Lockheed P-3 Orion, the predecessor of P-8.
The AN/APY-10 mechanically scanned radar is a development of Raytheon's AN/APS-149 radar.[2] Compared to the AN/APS-137, it is smaller in size, lighter, and uses less power.[1] The radar is optimized for maritime, 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 weather, synthetic aperture radar (SAR), inverse synthetic aperture radar (ISAR), periscope detection, and navigation. ISAR mode is said to be capable of both detecting, imaging and classifying surface targets at long range using a variety of resolutions.[1]
