Abstract

The radar imaging algorithms can be divided into three general groups as range migration algorithm (RMA), polar format algorithm (PFA) and chirp scaling algorithm (CSA). In this letter, we explore the RMA technique in X-band suitable for the strip-map mode of a synthetic aperture radar (SAR) system, and then propose a modified RMA to obtain better image resolution than is normally obtained using a conventional RMA. Finally, the reconstructed images generated using the modified RMA demonstrates that the proposed algorithm shows the better performance than a conventional RMA.
