AN/ZPY-3
AN/ZPY-3 Multi-Function Active Sensor (MFAS) is operating in the X-Band active electronically scanned array radar using a 360 degrees mechanical rotation. It was developed by Northrop Grumman for the US Navy’s MQ-4C BAMS, maritime surveillance UAV.
The AN/ZPY-3 MFAS sensor provides mode agility to switch between various surveillance methods. These include maritime-surface-search (MSS) mode for tracking maritime targets and inverse-synthetic-aperture radar (ISAR) mode for classifying ships. Two synthetic aperture radar (SAR) modes are used for ground searches; spot SAR for images of the ground and stationary targets and strip SAR for images along a fixed line.
