N2 - In this paper, the information theory is utilized to evaluate the jamming effect on SAR. Entropy could reflect the spatial detail information, and cross entropy could show the divergence and discrimination information of two kinds of probability distribution. We investigated the cross entropy and presented the improved cross entropy as an index to evaluate the jamming effect. The method was tested on SEASAT-A raw data. In the simulation, the entropy and improved cross entropy were compared, and the results show that this evaluation index, improved cross entropy, is available.
