Sar Images Improvements by Using The S-Method

Synthetic aperture radar processors are generally made with the stationary targets in mind, hence commonly used technique for the SAR signal analysis is a two-dimensional Fourier transform. Moving targets induce Doppler-shift and Doppler spread in the returned signal, producing blurred or smeared images. Standard techniques for these kinds of the problems are motion compensation and time-frequency analysis application. Both of them are computationally intensive. Here, we will present a numerically simple S-method based approach, already applied in the ISAR imaging. This approach improves readability of the SAR images what will be analytically proved and demonstrated on the simulated SAR setup
