摘要
飞行器腔舱结构是一种特殊散射结构,是复杂目标的主要散射源之一。对由介质雷达罩、雷达天线和其它高频部件构成的雷达舱以及由座舱罩及座舱的电子系统等构成的座舱系统,都是飞行目标头部区域的一个强散射源。由于舱内的结构千差万别,当电磁波进入舱内后,经过舱内诸多部件的多次散射,使其散射分析十分困难。本文采用能量分布调制法结合国内外座舱、雷达舱在一定区域内RCS的实验均值,分析了带有雷达舱结构的某型号导弹的RCS分布,在工程上有一定应用价值。
The construction of the aerocraft cabin and cavity is a special kind of scatter construction. It is one of the main sources of the complex targets. Both the radar-cabin composed of the medium radome, radar-antenna and other microwave devices, and the cabin system, the electronic system in the canopy and the driver, are the strong scatter sources in the head area of the flying target. Since the constructions inside these cabins are various, the scatter analysis for them is difficult after the electromagnetic wave radiates into the cabin and is scattered by many parts in the cabins. The method of the energy distribution modulation combined with the RCS experimentation median value of the cabin and the radar-cabin in the special area, is applied in the paper to analysis the RCS distribution of a kind of missile with the radar-cabin. The method is beneficial in the project application.
