The effectiveness and characteristics of noise jamming to synthetic aperture radar ( SAR ) are firstly analyzed through signal-to-jam ratio ( SJR ) in this paper , and the particularity of jamming a SAR and the factors which impact the effectiveness of noise jamming are studied .

本文首先从信号&干扰功率比（信干比）的角度分析了合成孔径雷达（SAR）噪声干扰的效果及特点，分析了对SAR系统实施噪声干扰的特殊性以及影响SAR噪声干扰效果的因素。

Comparison of SJR with Journal Impact Factor and H-index

SJR与影响因子、h指数的比较及SJR的扩展设想

According to SJR , the number of articles published by researchers in China has dramatically increased over the past ten years .

根据SJR，由中国科学家发表的论文数量在过去的10年显著增加。

This method is compared with classical noise jamming technique by means of SJR ( Signal to Jamming Ratio ) gain and jamming power gain of SAR system .

讨论了这种干扰方法对合成孔径雷达图像的干扰效果。

In fact , SJR finds China seriously behind the leading publishing countries Japan , the United Kingdom and the United States particularly in non-self citations .

事实上，SJR发现中国严重落后于领先的论文出版国家日本、英国和美国特别是在非自我引用方面。
