摘要
本文给出了有、无干扰时合成孔径雷达图像的统计模型以及图像间的统计关联,对合成孔径雷达图像的信息量以及干扰造成的图像信息损失进行了定量分析,从而建立了基于图像信息损失率的干扰效果指标,为合成孔径雷达干扰效果的综合定量描述提供了基础.
The statistical models of SAR image with and without jamming noise and the statistical relationship between these images are presented to give a quantitative analysis on Information measure of SAR image and its Infatuation loss caused by noise jamming.Thereby, an index based on the rate of information loss of SAR image is defined to make a synthetically quantitative description on the effect of SAR jamming.
