Chao Lü, Victor C. Chen · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1997
In this paper, we present a fast block time-recursive algorithm for the computation of short-time Fourier transform, and apply the algorithm to inverse SAR image processing. Simulation results are given and the computational complexity is discussed. The block time- recursive algorithm provides a fast vehicle for processing ISAR images on a real-time basis.
