摘　　要：以现有的目标获取性能模型NVESD为基础,分析杂波对于"人在回路"系统目标获取性能的影响,并针对激光干扰图像的特点,将杂波修正后的目标获取性能模型运用到激光干扰图像研究中,提出一种基于图像边缘概率尺度的激光干扰效果评价方法。该方法结合人眼的目标获取任务,从激光干扰如何影响人眼的搜索探测概率角度来研究激光干扰效果。对于CCD探测器的干扰实验结果表明,该方法能够反映激光干扰图像对于搜索探测概率的影响,较好地反映了激光干扰效果,从而验证了方法的有效性。Based on Night Vision and Electronic Sensors Directorate（NVESD） Target Acquisition Performance（TAP） models,the clutter impact on human-in-loop TAP is analyzed.Aimed at characteristics of laser jamming image,a modified TAP model based on clutter metric is applied to analyze laser jamming image.Then,an evaluation method for laser jamming effect based on Probability of Edge（POE） metric is proposed.The method combines with human target acquisition task and laser jamming effect evaluation is researched from the aspect of laser jamming influence on human search and detection probability.Experimental results of laser jamming to CCD show that the method can reflect the influence of laser jamming image on search and detection probability and can reflect laser jamming effect evaluation effectively.Hence,the validity of this method is verified.
