合成孔径雷达回波模拟器的建模仿真与系统设计，首先介绍了合成孔径雷达的高分辨力成像原理、SAR回波理论模型和几种SAR原始回波数据模拟算法。然后采用距离时域脉冲相干法对点目标的原始回波数据进行了模拟，并用经典RD算法对该回波进行处理，得到了期 望的结果，本文还用同样的方法对点阵目标的原始回波数据进行了模拟。 (Synthetic aperture radar echo simulator modeling and simulation system design, first introduced high resolution synthetic aperture radar imaging principle, the the SAR echo theoretical model and several SAR raw echo data simulation algorithm. Domain pulse coherent method and then using the distance of the original point target echo data simulation, and the echo processing using the classic RD algorithm to get the desired results, this paper also used the same way the original dot target back wave data were simulated.)
