Abstract
Wave domain SAR focusing can he exactly implemented hp means of the Stolt interpolation if rectangular geometries are assumed and targets are fixed. However, when target’s motion has to he considered, or when the sensor trajectory is not a straight line parallel to the sources, the Stolt interpolation is just an approximation. This paper introduces first an exact focusing technique for uniform target motion. Secondly, the Stolt interpolation is extended to non rectilinear motion of the sensors.
