舰艇间雷达电磁兼容预测与仿真分析

Electromagnetic Compatibility Prediction and Simulation Analysis of Ship Born Radar

雷达系统是水面舰艇最主要的无线电探测装备,但是当舰艇以编队出行时,编队内各舰艇的雷达系统却容易因为型号相同、工作频率相近、发射功率较大等原因,容易互相造成电磁干扰。这些电磁干扰严重影响了舰艇协同作战的效能,不利于电子装备性能的正常发挥。文中讨论了影响舰艇间雷达电磁兼容性的几个典型因素,分析了预测评估雷达间电磁干扰的预测和计算方法,建立了相应的数学模型,并进行了仿真计算。

Radar system is the main detection equipment for surface ships. However,when the ships are in formation,the radar system of each ship in the formation is easy to cause electromagnetic interference with each other due to the same model,similar operating frequency and large transmission power. These electromagnetic disturbances seriously affect the effectiveness of ship cooperative operation,which is not conducive to the normal performance of electronic equipment. This paper discusses several typical factors affecting electromagnetic compatibility of electronic equipment,analyzes the prediction and evaluation of electromagnetic interference between electronic equipment,establishes corresponding mathematical models,and performs simulation calculation.
