摘　　要：随着激光有源干扰技术的不断发展,激光半主动制导武器攻击精度受到严重影响,编码技术和波门选通技术等是常用的、有效的抗干扰措施。为了增大激光有源干扰难度,选通波门的宽度尽可能窄,而受到激光脉冲触发控制精度、运动物体的多普勒频移等因素的影响,选通波门的宽度不可能无限小。通过分析各因素的影响,得出理想的选通波门宽度取值范围。With the continuous development of active laser jamming technology,the attack accuracy of semi-active laser guidance weapons has been seriously affected.Coding technology and time-gate selection technology are common and effective anti-jamming measures.In order to increase the difficulty of active laser interference,the width of the time-gate should be as narrow as possible.However,the width of the time-gate cannot be infinitely small due to the influence of laser pulse trigger control accuracy,Doppler frequency shift of moving objects,etc..In this paper,the ideal width range of time-gate is obtained by analyzing the influence of various factors.
