摘　　要：针对高功率微波辐照下雷达方舱内电子设备的响应和毁伤效应等实际问题,通过建立雷达方舱和舱内电缆模型进行了辐照仿真分析。结果表明,高功率微波信号在进入方舱时,方舱起到一定的滤波作用,类似带通滤波器;雷达方舱和舱内设备的反射会影响方舱内场强分布和极化,造成方舱内电场分布不均匀,各向异性降低,但尚未达到混响室程度;通过仿真概略计算了方舱内信号分布和传输特性;方舱内电缆耦合信号电压基本在同一个数量级,超宽谱信号辐照影响主要以扰乱为主。针对上述影响,提出了相应加固措施,可为雷达在高功率微波武器攻击下进行后门防护加固提供理论支撑。Aiming at the practical problems of the response and damage effect of the electronic equipment in the radar shelter under high power microwave irradiation,the radiation simulation analysis is carried out by establishing the radar shelter and the cable models in the shelter.The analysis results show that when high-power microwave signals enter the shelter,the shelter plays a certain filtering role,which is similar to band-pass filter.The reflection of the radar shelter and the equipment in the shelter will affect the field intensity distribution and polarization in the shelter,resulting in uneven distribution of the electric field in the shelter and anisotropy decreased,which is different from that in the reverberation chamber.The signal distribution and transmission characteristics in the shelter are calculated by simulation.The voltage of cable-coupled signal in the shelter is basically at the same magnitude,and the mainly influence of UWB HPM irradiation is disturbing.In view of the above effects,the corresponding reinforcement measures are put forward,which can provide theoretical support for the rear door protection reinforcement of radar under the attack of high power microwave weapons.
