摘要
用４ｍｍ波段测量系统对飞机模型进行了弹目交会动态雷达截面积（ＲＣＳ）统计测量研究，并详细地研究了飞机目标近场区的各局部部位的概率统计分布规律，其结果显示出和远场区分布有着非常大的差别。此外，还用矢量相减技术对雷达目标进行了幅相特征信息提取研究，取得了满意的结果。
Using 4mm wave band system, the statistical properties of dynamic RCS of aircraft model in the area of missile target engagement are investigated, the probability distributions for all local positions of aircraft in near field are also analyzed. The results show that the distribution differs significantly from that of far field. In addition, the extraction of information about amplitude and phase characteristics to radar target is studied by the techniques of vector substract. The results are satisfactory.
