摘　　要：为客观评价超宽谱高功率微波对某型连续波多普勒引信的干扰能力,构建了引信辐照效应试验系统,并开展了辐照效应试验。试验结果表明:受试引信最强能量耦合姿态为引信竖直向上,弹体轴线与辐射场传播方向垂直,三角环天线平面垂直于辐射场传播方向;主要能量耦合通道为弹体;重复频率越高,发火电路端耦合电压越大,且同为82kV/m的辐照场强,单次、10Hz重频、20Hz重频和50Hz重频触发条件下耦合信号电压值分别约为66.5,69.4,71.5,74.6V;在157kV/m干扰场强范围内,超宽谱不会造成引信意外发火,但会影响引信检波电压和工作电流等性能参数。To evaluate the anti-jamming capability of a certain continuous wave Doppler fuze,an experiment system for fuze irradiation is developed,and typical fuze experiments are performed under ultra-wide spectrum high power microwave(UWSHPM)irradiation.Experiment results show that the strongest coupling pose is when the fuze is vertically upward,and the bomb body axis and the antenna plane are perpendicular to the radiation field propagation direction.The bomb body is the main energy coupling channel.The higher the repetition frequency,the bigger the coupling voltage of the firing circuit.At 82kV/m field strength,the coupling voltage of the repetition frequency in single,10 Hz,20 Hz and 50 Hz states are 66.5,69.4,71.5and74.6V,respectively.At 157kV/m field,the fuze will not be fired in any state.However,the field of UWSHPM can affect the capability parameters,such as demodulation voltage and working current.
