地海面杂波特性对主要采用下视工作方式的机载脉冲多普勒 (PD)雷达具有十分重要的影响 .本文在具体分析PD雷达工作体制的基础上 ,详细研究了载机处于任意飞行姿态下 ,利用三维数字地形高程图和对应地物散射特征分类 ,模拟产生多频段多极化雷达距离 多普勒杂波图的方法 .仿真结果证明了该算法的有效性
Ground clutter characteristics have a very important impact on airborne pulsed Doppler (PD) radar, which mainly uses down-view working mode.Based on the detailed analysis of PD radar working system, Attitude, the method of generating multi-band multi-polarization radar range Doppler clutter is simulated by using the three-dimensional digital terrain elevation map and the corresponding feature scattering classification.The simulation results show the effectiveness of the algorithm
