Abstract:

Sandia National Laboratories in collaboration with General Atomics GA has designed and built a high resolution, light-weight, Ku-band Synthetic Aperture Radar SAR known as Lynx. Although Lynx can be operated on a wide variety of manned and unmanned platforms, its design is optimized for use on medium altitude Unmanned Aerial Vehicles UAVs. In particular, it can be operated on the Predator, I-GNAT, and Prowler II platforms manufactured by GA. U The radar production weight is less than 120 lb and operates within a 3 GHz band from 15.2 GHz to 18.2 GHz with a peak output power of 320 W. Operating range is resolution and mode dependent but can exceed 45 km in adverse weather 4 mmhr rain. Lynx has operator selectable resolution and is capable of 0.1 m resolution in spotlight mode and 0.3 m resolution in stripmap mode, over substantial depression angles 5 to 60 deg and squint angles broadside plus or minus 45 deg. Real-time Motion Compensation is implemented to allow high-quality image formation even during vehicle turns and other maneuvers.
