摘要
为了研究雷电电磁脉冲场对连续波多普勒引信安全性能的影响,确定引信的能量耦合通道和效应规律,构建了引信雷电电磁脉冲辐照试验系统,并开展了该引信雷电电磁脉冲辐照效应试验。试验结果表明: 受试引信最佳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; 不同辐照波形下引信的临界干扰场强不同,在配用152 mm弹体时,1.2/50,5.4/70,0.25/100和10/350 μs波形的临界干扰场强分别约为74,60,65和75 kV/m。雷电电磁脉冲对受试引信的作用机理为: 辐射能量通过弹体耦合到执行电路输入端,由于感应信号脉冲宽度满足触发脉冲宽度的最低要求,从而推动引信执行电路误动作。
Abstract
In order to study the security effect on a certain radio fuze of lightning electromagnetic pulse (LEMP), and confirm the energy coupling channel and the effect rules, an experiment system is constructed and LEMP irradiation experiments are done. Experiment results show that the best coupling pose is that 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. Different irradiation wave has different threshold interference field. Under the 152 mm bomb body, the threshold interference fields of the irradiation waves of 1.2/50, 5.4/70, 0.25/100 and 10/350 μs, are about 74, 60, 65 and 75 kV/m. The effect mechanism of LEMP is that the irradiation energy couples to the input of the executive circuit. The pulse width of the coupling signal satisfies the requirement of the startup pulse width, leading to the miss-action of the executive circuit.
