Abstract

In order to improve the imaging performance of the airborne Ultra-wideband synthetic aperture radar, the imaging algorithm is researched. Firstly, the characteristics of the airborne Ultra-wideband synthetic aperture radar and the key technical problems of imaging are analyzed. Then, aiming at its key technical problems, a Chirp Scaling imaging algorithm is adopted to correct range migration, reduce strong coupling, eliminate space-varying characteristics, and solve the dependence of range compression on azimuth frequency, etc. Finally, the traditional range-Doppler imaging algorithm and the Chirp Scaling imaging algorithm are applied to the airborne Ultra-wideband synthetic aperture radar imaging, and simulation and comparative analysis are carried out. The simulation results show that the echo signal strength of Chirp Scaling algorithm in range and azimuth is obviously better than that of range-Doppler algorithm, and Chirp Scaling algorithm is more suitable for the airborne Ultra-wideband synthetic aperture radar imaging system.
