Abstract

A signal processing apparatus for use in SAR radar. The signal processing apparatus uses a new method of processing SAR images, primarily for wide band SAR. The new method is based on the numerical unfolding of differential equations along the flight path. The method makes motion compensation possible and can be used along a curved flight path and irrespective of the acceleration of the aircraft. Moreover, the method makes real time processing possible.
