摘要
根据对飞行器跟踪低空目标时所受的多路径干扰的分析,给出了基于多闪烁点源复杂目标和镜像目标的雷达散射截面积(RCS)模型以及地面散射系数模型。对整套模型方案进行的仿真实验表明,实验结果与实测数据吻合较好。对飞行器超低空飞行时抑制镜像干扰问题的解决有重要的参考价值。
According to the analysis of multi-path interference when the flying vehicle is tacking low-altitude target, the RCS model of complex target and image target based on multi-reflect-point and the reflectance model of the ground are presented. These models have been verified through simulation experiment. The results of experiment are in good agreement with the data measurement. There is an important reference value to suppress interference of image target.
