摘要
研究了光电干扰设备对光电制导系统干扰效果的评估方法,针对3种不同的干扰试验方法分别提出了相应的干扰效果评估准则.对于仿真试验,可以根据实施干扰后,制导武器的脱靶量是否超出未受干扰时正常制导精度的3倍,判定干扰是否有效,并依据干扰成功率的大小划分干扰等级;对于实弹干扰试验,可以根据脱靶量是否超出正常制导精度的3倍,或杀伤半径来判定干扰是否有效;对于模拟飞行干扰试验和地面试验,可以根据导引头的跟踪脱靶量是否超出导引头正常跟踪精度的3倍,或导引头在靶平面上的跟踪脱靶距离,是否超出应用该种导引头的制导武器的杀伤半径来判定干扰是否有效.
The paper is devoted to a systematic study on the methods for evaluating and testing the jamming effectiveness of electro-optical jamming devices on electro-optical guided weapons. The evaluation rules of jamming effectiveness for three different test methods are presented respectively. For the simulation test, whether the miss distance of the guided weapon under jamming is greater than three times its guidance accuracy （standard deviation） when there is no jamming is proposed as the criterion for whether the jamming is effective or not. Jamming grades are determined according to the jamming success rate for numbers of jamming tests. For the ball firing test, the criterion for jamming effectiveness is whether the miss distance of the guided weapon under jamming is greater than its kill radius for specific targets or three times its guidance accuracy when there is no jamming. For the flight and ground tests with seeker simulators, the criterion for jamming effectiveness is whether the tracking error of the seeker under jamming is greater than three times its tracking accuracy （standard deviation） when there is no jamming, or whether the tracking missdistance of the seeker at the destined impact point is greater than the kill radius of the guided weapon which employs the seeker.
