Ground Moving Targets Refocusing Algorithm for Spotlight SAR Data

A new target-subpatch technique based-on re-centering phase computation of previously recorded raw data will be implemented to the Spotlight SAR data in order to obtain refocused moving targets. Target detection capability is ensured by Change Detection Technique. At the next step, re-organize the raw data by selecting and arranging target focusing center with a new technique based on re-centering phase computation to a reference point for each moving target is applied. Finally, Range Doppler Algorithm will be applied to each re-organized raw data to obtain highly focused moving targets individually.
