| 摘 要： | 精确计算机载雷达地杂波功率一般是对等距离—等多普勒单元网格求积分,但其面积单元复杂多样,计算非常复杂。文中在分析等距离等多普勒分布特点的基础上,提出一种仅沿距离积分的计算杂波功率的方法。利用该方法仿真机载前视气象雷达风切变模式下地杂波功率谱和回波信号,还分析杂波功率谱受载机速度、波束方位和俯仰等参数影响的变化规律,仿真分析结果与飞机实际测量数据相符。

| Abstract: | The precise computation of ground clutter power for airborne radar is involved with integrating on the range-Doppler cells.But the process is very complex,which needs to resolve boundary of integration cells.Based on the distribution characteristic of iso-range and iso-Doppler,the computation of clutter power integrated on the range is described in detail.The ground clutter power and echo signal for airborne forward-looking weather radar is simulated.It analyzes the variation of clutter power influenced by ... |
