基于探测性能的舰载雷达电磁兼容分析

Electromagnetic Compatibility Analysis of Ship-borne Radar Based on Radar Detection Performance

针对舰船编队时同种雷达较多,相互之间存在电磁兼容影响的问题,利用描述雷达探测性能的最大作用距离的衰减来描述雷达系统中同频段间的电磁兼容程度。首先,分别建立相同工作频段、不同频率雷达间的电磁兼容模型;得到整雷达系统的电磁兼容模型。然后,通过仿真定量分析了模型的雷达间距、压制系数、灵敏度等重要参数对电磁兼容的影响,对发挥协同作战雷达的最大效益提供了数字化分析依据。

Aimed at the electromagnetic compatibility（ EMC） problems between same working band radars on fleet battle ships, ra-dar detection performance such as maximum radar range is used to describe the EMC degree between the radars in radar system. The EMC degree model of entire radar system can be gotten by establishing EMC model of every two radars.Through the simula-tion, the relationship is analysed between the degree of EMC and several important parameters in the model such as the distance between the radar and so on which provides a digital basis for analyzing maximum benefit of the radar in coordinating combat.
