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.
