摘要
多波束工作模式是一种新的合成孔径雷达(SAR)工作模式,既可以满足高分辨率的需要,又可以满足宽测绘带的要求,因此具有很高的研究价值和广泛的应用前景。文中提出了多相位中心多波束SAR的回波模型,给出了仿真方法;并以三波束星载SAR为例,通过仿真实例验证了该方法的有效性。
Multiple beam mode is a new operation mode for a SAR, satisfying the requirements of super-spatial resolution and wide swath at the same time. So it has wide application prospect and is worth of being studied. In this paper, a signal model of DPCM and simulation method is proposed. Finally, an example of three-channel DPCM Spaceborne SAR is presented for varifying the method.
