摘　　要：介绍了激光定向干扰红外探测系统的干扰机理及波段内激光定向干扰的主要干扰方式。以InSb红外探测成像系统为研究对象,开展了典型条件下的波段内脉冲激光定向干扰试验,分析了InSb面阵探测器对波段内脉冲激光干扰的响应特性,获取了探测器在脉冲激光干扰下的损伤模式和损伤阈值,为后续深入研究激光定向干扰效能奠定基础。The interference mechanism of laser directional jamming to an infrared detection system was investigated in this study,and the chief jamming mode of the above-band laser was discussed.A pulsed-laser jamming experiment was conducted using the infrared detection system based on an indium antimonide(InSb)focal plane array(FPA)detector,and the response characteristics of the InSb FPA detector with above-band pulsed-laser jamming was analyzed.The failure mode and failure threshold of the InSb FPA detector were derived.The results provide a basis for further research into directional infrared countermeasure performance against infrared imaging guided weapons.
