Study on Azimuth Signal Processing of Single Phase Center Multiple Beams Synthetic Aperture Radar

采用单相位中心多波束(SPCMB)技术是实现高分辨率宽测绘带合成孔径雷达系统的一种技术途径。该文介绍了SPCMB技术的原理,给出了这种模式的系统模型和信号特征,提出了方位向信号处理的方法,并利用星载点目标仿真和机载原始数据模拟的方法验证了该信号处理方法的可行性。

Single Phase Center Multiple Beams(SPCMB) technique is one of solutions to implement high resolution wide swath spaceborne synthetic aperture radar systems. The system model and signal characteristics are described based on the introduction to the principle of single phase center multiple beams technique in the paper. A method of azimuth signal processing is presented, and is proved by spaceborne point-target simulation and airborne raw data simulation.
