Abstract

In order to detect and imaging the moving boat monitoring ships from the dynamic ocean surface correctly in the image of Synthetic Aperture Radar, a novel approach based on fractional Fourier Transform with the Dual Receive Antenna SAR data was introduced. The traditional method of motion parameters estimation and focusing was modified, and the processing and analysis to improve the performance of estimation of FM rate introduced by the along-track moving of the boat, the time-frequency distribution was provided and the accuracy estimation by Fractional Fourier Transform was given, then the refocusing method was proposed. The experimental result shows that the proposed method is very effective.
