摘　　要：针对激光与光电探测器两种相互作用方式,选择四种常见的激光脉冲波形,建立简单数学模型,计算了光电探测器接收到的激光脉冲能量和脉冲激光在探测器上的有效持续时间,并据此分析激光脉冲时域特性与光电探测器的响应关系.计算结果表明,不同的激光脉冲波形引起的光电探测器的响应会有差异,并且,相对较长的大能量激光脉冲波形可能在探测器中引起较好的作用效果.Concerning two generally adopted ways in active laser jamming photodetector, a simple mathematical model is set up to calculate both the laser energy received by the target detector and duration of laser beam illuminating on it with respect to four commonly available laser pulse profiles ,so as to estimate the response of the detector to active laser illumination. Numerical results show that the response of the detector varies with the laser pulse profiles and in general the laser pulse profile with higher energy and relative longer pulse duration is more likely to generate better jamming results on the detector.
