Back Projection Version of Subspace Detector SAR Processors

Abstract : A new version of the signal subspace detector synthetic aperture radar (SSDSAR) processor developed in [1] is proposed. Actually, the SSDSAR processor can be divided in two different parts: a subspace basis computation part and an imaging part. The new version proposed here consists in performing the imaging part on fast-time compressed data and not raw data in order to reduce the computational cost from O(N4) to O(N3). We note that this new processor is the subspace detector version of the classical back projection SAR processor.
