摘　　要：为了同时获得实装对抗的高可信度和数学仿真大样本的优点,提出了基于激光导引头实物对抗数据的光电对抗效果评估技术,分析了该种实验方法的主要误差因素。根据目标漫反射特性和直射式激光干扰设备特点,建立了激光导引头处目标漫反射激光能量密度模型和激光导引头处直射式激光干扰设备激光能量密度模型。采用数值计算方法,分析了激光导引头处目标漫反射激光能量密度误差分布规律和激光导引头处直射式激光干扰设备激光能量密度误差分布规律。最后利用实际试验过程,计算了该种实验方法下激光导引头接收到的目标漫反射激光能量密度和直射式激光干扰设备激光能量密度的误差,证明了该实验方法的有效性。A simulation test method on electric-optic countermeasure to real laser seekers was proposed to get high reliability of real laser seeker and sample quality of simulation, and the major error factor was found. It was diagrammatic how the process of test worked, and the steps of test were given. According to the characteristic of diffuse reflection target and direct irradiated equipment, the models of laser energy density for diffuse reflection target and direct irradiated equipment at the point of laser seeker were established, and the error distribution principle was analyzed numerically. Besides, it was defined how to get the valid distance with error. The real jamming tests were performed to a real seeker by an electro- optic countermeasure system. The conclusion is that the jamming to laser guided weapon was valid by the electro-optic countermeasure system, and the valid distance also was given. The method was proved to be effective by the tests.
