摘　　要：烟幕干扰作为现代战场常见的无源干扰方式,具有优良的光电对抗效果、较强的战术应用机动性和较高的效费比。针对基于图像的烟幕干扰定量评估研究不足,本文从跟踪的角度出发,对烟幕干扰下目标的红外成像使用灰度特征、基于LBP的纹理特征、类哈尔矩形特征、方向梯度直方图特征以及深度特征5种方法进行特征提取,通过将特征提取结果与主观评分进行相似性计算,得出不同图像特征对烟幕干扰下目标的表征能力。通过对8组外场试验所得数据的分析验证,得出结论,对烟幕干扰下目标表征能力较为优秀的三种特征分别是方向梯度直方图特征、类哈尔矩形特征以及深度特征。As a common passive interference method in modern battlefield,smoke screen jamming has excellent photoelectric countermeasure effect,strong tactical application mobility and high cost effectiveness ratio.In view of the lack of research on quantitative assessment of smoke screen interference based on images,five methods are used to extract features from infrared images of targets under smoke screen interference,including grayscale features,LBP based texture features,Haar like rectangular features,directional gradient histogram features and depth features from the perspective of tracking.By calculating the similarity between the feature extraction result and the subjective score,the ability of different image features to characterize the target under smoke screen interference is obtained.Through the analysis and verification of the data obtained from eight sets of field tests,it is concluded that the three features with better target representation ability under smoke screen interference are the directional gradient histogram feature,the Haar like rectangle feature and the depth feature.
