摘　　要：针对某系留无人机超短波侦察接收系统,实际使用效果不理想的电磁兼容性问题进行分析排查整改。由于无人机系统自身产生的干扰噪声被系统的天线接收到,从而导致该系统出现电磁干扰问题影响使用性能。针对系统出现的电磁干扰问题进行了详细的分析排查,并采取相应的整改措施。整改后,系统电磁干扰明显降低,性能明显提升,达到预期效果,为此类设备的电磁兼容设计整改提供一定的参考。Power line filtering is an important part of EMC design.There are many EMC problems caused by power line in electronic equipment.This paper introduces the basic knowledge of power line filter,focusing on the electromagnetic compatibility design and rectification experience for many years,and introduces several key points that should be paid attention to in power line filter design.
