摘要：

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(N-4) to O(N-3). We note that this new processor is the subspace detector version of the classical back projection SAR processor [2].
