Inflight measurement of antenna pattern for spaceborne SAR using encoding transmitters

文中提出利用多个编码发射机在轨测量星载SAR接收天线二维方向图的技术:介绍测量原理,推导信号生成、接收、多普勒补偿及相关处理的关键算法。计算机模拟测量结果验证该方法的可行性.

A new method of antenna receiving pattern measurement for spaceborne SAR using encoding transn-dtters are described in this paper. The principle is described and the arithmetic of signal processing is derived. The results of simulation prove that this measurement method is feasible.
