干扰条件下的红外目标检测方法研究

Research on Infrared Target Detection Method under Jamming Condition

为了实现红外诱饵弹干扰下的红外目标检测,提出了一种基于相对位置的综合决策算法。该算法首先使用多尺度形态学去除背景和诱饵的高亮度影响,在此基础上分别进行基于特征块的阈值分割以及边缘检测,根据目标和诱饵的物理、运动特征的差别分别检测出候选目标区域,并对该区域进行基于相对位置的综合决策,判定出真实目标的位置。结果表明,使用基于相对位置的综合决策得到的结果远优于单独使用这两种方法得到的检测结果。

In order to detect the infrared target under infrared decoy jamming,a comprehensive decision-making algorithm based on relative position is proposed. The multi-scale morphological method is used to remove the high brightness of the background and decoys. The threshold segmentation based on the feature block and edge detection are carried out to detect the candidate target area according to the difference of physical and movement characteristics of target and decoys. Using the comprehensive decision-making method by relative position to detect the candidate target area,and the real target position is obtained. The experimental results show that the comprehensive decision-making method based on relative position is much better than other methods.
