Abstract
High resolution synthetic aperture radar system will produce aliasing problem in the sliding spotlight mode, we propose a solution based on sub-apertures splice to solving the program, the simulation and analysis of airborne mode are given. The method use the sub-aperture division, respectively, each aperture frequency shift, scaling, compression distance, azimuth compression performed prior to stitching, the data will be spliced after azimuth compression and windowing. Simulation results show that the algorithm can effectively solve the problem.
