摘要
欺骗干扰效果评估是SAR对抗领域的热点和难点问题。基于新型欺骗干扰的特点,给出欺骗度和压制度的表征方式,并提出一种将欺骗度和压制度相结合的综合评估方法。该方法不仅可利用干扰前后目标轮廓特征的变化描述欺骗干扰逼真度,而且根据图像ROI压制度的分析实现对欺骗度的验证,并结合人工决策模式得到了干扰样式优选的判决条件。实验结果表明,这种评估方法不仅能够有效地对新型欺骗干扰的对抗效果作出评价,而且引入了一定的信息反馈机制,使得评估结论的针对性更强,可靠性更高。
Evaluation of suppressive jamming effect is one of the hot and difficult problems in the area of SAR electronic countermeasures（ECM）.Two concepts of deceptive degree and suppressive degree based on characteristics of new deceptive jamming effect are presented in this paper,and then a synthetic evaluation method combining deceptive degree with suppressive degree is proposed.It can not only describe the jamming fidelity by utilizing change of target contour features,but also validate the deceptive degree according to analysis of suppressive degree based on region of interest（ROI） in image,with a human decision mechanism to get determinant conclusion of optimization choice in several jamming modes.The experiments results show that the proposed method can effectively evaluate new deceptive jamming effects,and the evaluation conclusions are much more pertinent and credible through introducing an information reactive mechanism.
