AN/ZPQ-1 (TESAR) is operating in Ku-Band is a small, light, low-cost sensor for use on Unmanned Aerial Vehicles (UAV), e.g. for the U.S. Air Force's UAV “RQ-1 Predator”. It is a ground-sweeping radar which can detect objects as small as one foot in size and pick out those which are moving from those which aren't. The radar provides two SAR stripmap modes and a spotlight mode.
The focused SAR imagery is formed on-board the Predator UAV, compressed and sent to the Predator Ground Control Station over a Ku-Band data link.
ZPQ-1 is being replaced on newer UAVs with more modern radars such as the AN/APY-8 Lynx SAR and STARLite radar.
