摘　　要：针对超宽带高功率微波脉冲辐照下雷达前门耦合特性进行探索,通过理论分析、软件仿真、辐照实验,对抛物面雷达天线的响应特性进行了研究。实验结果表明:由于天线的带通滤波作用,与窄带信号辐照相比,在接收超宽带脉冲信号过程中,会导致输出信号频谱变窄、时域延拓、峰值电压变小,并伴有振荡衰减的尾瓣,耦合输出信号表现为非线性失真。由于在耦合过程中丢失部分能量,毁伤效果降低。The law of front door coupling effect of radar under UWB-HPM irradiation was explored.And the response characteristics of parabolic radar antenna were studied by theoretical analysis,software simulation and irradiation experiment.The results show that compared with NB-HPM,due to the filtering effect of parabolic antenna,the coupled output signal will be nonlinear distorted,spectrum narrowed,time domain signal extended,peak voltage decreased,and have a oscillation attenuation tail,which affects the damage effect.
