WISP – Wide-Area Infrared
Sensing with Persistence
WISP detects and tracks surface and air threats in the surroundings. It provides 360-degree, hyper-hemispherical coverage: 360-degrees in azimuth and from 35-degrees below the horizon to the zenith in elevation (straight up above the sensor). It is a new sensing system with capability that spans across the traditional features of thermal infrared cameras and radars. Typical narrow field-of-view thermal infrared cameras, a WISP image covers the complete surroundings.
Unlike a radar, WISP is a completely passive sensor that relies only on the self-emission of the objects to detect and track them at long range. Since it uses passive sensing, WISP is not easily detected or jammed by others.
