摘要 研究了烟幕干扰设备对光电成像系统和光电制导系统干扰效果的评估方法,分别提出了相应的干扰效果评估准则。烟幕对观瞄用光电成像系统干扰效果的定性评估可以按照干扰对目标识别的影响程度划分为3个等级,定量评估可以采用实施干扰前后图像之间的相关函数作为评估指标,按照相关函数值的大小将干扰效果划分为3个等级;烟幕对跟踪用光电成像系统的干扰效果可以根据光电成像系统能否输出有效跟踪脱靶量以及脱靶量是否超出正常跟踪精度的3倍判定干扰是否有效。对于光电制导系统,可以根据实施烟幕干扰后制导武器的脱靶量是否超出正常制导精度的3倍或杀伤半径判定干扰是否有效,并根据干扰成功率的大小划分干扰等级。 This paper devoted to the methods for evaluating the jamming effectiveness of smokescreen jamming devices on electro-optical imaging systems and electro-optical guided weapons. The evaluation rules of jamming effectiveness were presented. For smokescreen jamming upon the electro-optical imaging system for observing or aiming, the jamming effects are graded into three rates according to the degrees of interference to target identification. Quantitatively, the correlation function is proposed as an evaluation index for smokescreen jamming effectiveness and the jamming effects are graded into three rates according to the correlation function of the two images before and after being jammed. For smokescreen jamming upon the imaging system for automatic tracking, the proposed criterion for jamming effectiveness is whether the imaging system under jamming could produce effective tracking errors, or its tracking error under jamming is three times greater than its tracking accuracy when there is no jamming. For smokescreen jamming upon the guided weapon, the proposed 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 greater than its guidance accuracy (standard deviation) when there is no jamming. The jamming grades are determined according to the jamming success rate for a number of jamming tests.
