Abstract:
This paper presents a highly efficient SAR processing algorithm for stripmap data. The algorithm is based on a dispersive filtering algorithm, operating on very short range time slices in the range-Doppler domain. The short range duration of each slice allows approximations that lead to a very efficient processing algorithm based on very short Fast Fourier Transforms.
