烟幕对光电制导目标识别能力干扰效果研究

Research on the jamming effects of smoke screen on target identification capability of photoelectric guidance

光电制导武器对目标的战场生存造成了巨大威胁,烟幕是对其有效干扰的一种重要手段。通过分析烟幕对可见光和红外辐射的作用原理,搭建了烟幕干扰实验平台,获得了烟幕对红外成像制导和景象匹配制导的干扰数据。对实验数据分析处理后的结果表明:烟幕能够有效降低红外成像制导系统的作用距离和目标识别能力,严重影响景象匹配制导算法的性能,甚至使其完全失效。

Photoelectric guidance weapon greatly threatens the target,s survival in battlefield.However,smoke screen is an effective jamming means to photoelectric guidance weapon.Through analyzing the working principle of smoke screen on visible light and infrared radiation,a interference platform of smoke screen is established and the interference data of smoke screen on infrared imaging guidance and scene matching guidance systems are obtained.The results show that the smoke screen can effectively decrease the operation distance and target identification capacity of infrared imaging guidance system,and can severely weaken the performance of scene matching guidance algorithm,even can cause the algorithm's complete failure.
