Abstract :
This paper deals with phase preserving focusing for very low resolution ScanSAR. Conventional techniques get ScanSAR focusing by exploiting the SAR matched reference, and compensate scalloping by an inverse antenna weighting. Yet, this approach introduces a space-variant distortion in the focused impulse response (IRF). A rather different focusing technique is then proposed, where the set of space-variant focusing kernels is computed by means of Wiener deconvolution. They perform ScanSAR focusing and descalloping at one time, achieving the finest resolution and without distorting the impulse response
