AN/ZPY-1
The radar is under contract to the U.S. Army Communications and Electronics Command for its ERMP General Atomics MQ-1C Gray Eagle Unmanned Aerial System and is manufactured by Northrop Grumman.Weight was reduced by combining the radar power supply and processor and incorporating a Systron Donner inertial system.The original STARLite radar is used on the MQ-1C Gray Eagle and the Lockheed Martin Persistent Threat Detection System (PTDS) aerostat.The company is proposing the lighter version for integration onto small UAVs, including the RQ-7B Shadow, the MQ-8C Fire Scout, and the TigerShark UAS.In addition to SAR/GMTI, it has a dismount moving target indicator mode that can track a person walking on the ground from a range of 4.3 nmi (8.0 km; 4.9 mi).
