摘　　要：两部舰载雷达天线的主瓣对准时将产生严重的电磁干扰现象,并造成舰载雷达作战效能的下降。针对这一问题,本文分析了雷达在空域上产生互扰的条件及雷达天线转速与主瓣互扰的关系,建立了在不同条件下雷达主瓣互扰概率的数学模型。用Matlab对该模型进行仿真分析,得出雷达间互扰概率随天线相对转速的变化图,最后提出降低主瓣互扰概率的具体措施。When the main lobes of the antennas of the two shipborne radars are pointing to each other, severe electromagnetic interference will occur and hence the radar operational efficiency will reduce. In order to solve the problem, the conditions of generating radar mutual interference in airspace and the relationship between the antenna relative rotation speed and the mainlobe mutual interference are analyzed. Besides, the mathematical model of the mutual-interference probability of radar mainlobes under different circumstances is set up. The simulation based on Matlab demonstrates the relationship between the mutual-interference probability and the antenna relative rotation speed. Finally the methods of lowering the mutual-interference probability of radar mainlobes are proposed.
