复杂电磁环境对雷达与指控系统的影响

防空群雷达与指控系统在信息传输、融合与处理过程中的媒介是电磁波，其作战效能的发挥在复杂战场电磁环境下面临严峻挑战。结合部队维修保障经验，归纳了防空群雷达与指控系统在复杂电磁环境下演习和训练中反复出现的3类问题，设备出厂性能检验合格，实际投入系统使用效果不佳；雷达与指控系统内部不能同时开机，自扰互扰问题严重；敏感设备、单元及端口极易受高功率电磁能量损伤。由此总结出一类共性问题——缺乏系统级电磁环境效应综合评估方法。最终给出解决问题所需开展的关键技术研究。

Effects of Complex Electromagnetic Environment on Radar and C2System

Information transmission, fusion and processing of radar and command and control (C2) system in air-defense group is based on electromagnetic wave. Its effectiveness faces with huge challenge under the battlefield complex electromagnetic environment. Combining with experiences in unit maintenance support, three problems appeared repeatedly in maneuvers and trainings were summarized, which were dissatisfied actual use effects of qualified products by leaving factory performance examination, serious interference of the two equipments causing unable to work simultaneously, and sensitivity unit easily damaged by high power electromagnetic energy. It was summarized that the common problem is short of system level electromagnetic environment effect assessment method. Finally, the key problem-solving technologies were put forward.
