  • Abstract
    The information theory is utilized to investigate the problem of evaluating the effect on jamming SAR. By the means of the entropy to analysis SAR image, we understand that the cross entropy could show the divergence and discrimination information of two kinds of probability distribution. We try the cross-entropy as the rule for SAR jamming effects evaluation. Simulation results of the interference effect evaluation on the SEASAT-A raw data are presented, and the results show that the evaluation rule is effective.
