摘　　要：腔体电磁效应是多个散射体发生相互作用的结果,它使得周围区域的电场强度在某些频点突然增大。对于舰船平台上的武器装备,腔体电磁效应的出现将会导致一系列的电磁安全性问题。本文对腔体电磁效应进行了分析,获取了腔体电磁效应与腔体结构的几何尺寸、天线发射功率之间的相关性,提出了相应的控制方法。同时,采用数值仿真分析方法,对本文提出的腔体电磁效应控制方法的有效性进行了验证。仿真结果表明,本文提出的方法可以有效地减小或消除腔体电磁效应。The interaction of multiple conductors can cause cavity electromagnetic effect.It could make the electromagnetic field increase suddenly in some frequencies.For the weapon equipments located on the naval ship,the cavity electromagnetic effect will bring a series of problems of electromagnetic safety.The cavity electromagnetic effect has been analyzed.The relationship between cavity electromagnetic effect and dimensions of cavity and the relationship between the effect and the power of transmitting antenna have been obtained.Some controlling methods have been provided.Moreover,the validity of the controlling methods has been validated based on numerical simulation method.The results of simulation indicate that the controlling methods can decrease or eliminate cavity electromagnetic effect.
