Accurate moving target location in SAR imagery

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 (sub metre) images free from the distortion caused in conventional SAR imagery by moving targets, and allows the accurate location of both stationary and moving objects.
