Non-linear synthetic aperture radar techniques

The non-linear synthetic aperture radar (SAR) technique uses a combination of platform manoeuvre and novel processing to separate the effects of a target's radial velocity and cross-range displacement, giving accurate estimates of both. The technique provides high resolution images free from the image distortion caused in conventional SAR imagery by moving targets, and allows the accurate target location of both stationary and moving objects. The technique also allows the platform to fly a wide range of planned and unplanned manoeuvres, improving platform survivability in potentially hostile environments
