高功率微波武器攻击雷达的可行性研究

Feasibility of HPM weapon attacking radar

高功率微波武器是对现代雷达的第五种威胁。分析了高功率微波武器进攻雷达的途径,阐述了HPM损伤雷达接收机前端的机理,通过计算研究了HPM损伤接收机前端的可行性。计算结果表明,10GW的窄带微波弹,当波束对准雷达天线主瓣时,可损坏雷达接收机保护电路;而对于超宽带微波弹,功率为1GW时即可穿越放电管而损伤限幅器。早期雷达抗HPM损伤能力较差,1GW的微波弹,不管是窄带还是超宽带,都可以损伤其接收机。

The high power microwave （HPM） weapon is the fifth threat to modern radar, The path of HPM weapons attacking radars is analyzed..The mechanism of HPM damaging the front-receiver of radars is expounded,and its feasibility is studied by computing. The computing results show that the narrowband HPM bomb whose power is 10 GW can damage the protection circuit of radar receiver when its beam aim at the mainbeam of radar antenna and the ultra-wideband （UWB） HPM bomb whose power is 1 GW can get over the discharge tube and damage the limiter. The early radar＇ s ant-damage ability is so weak that the HPM bomb whose power is 1 GW,no matter the narrowband or UWB, can damage its receiver.
