从信息战角度出发，对电子侦察卫星作了简要介绍，在归纳了电子侦察原理的基础上提出了完全侦察、非完全侦察和病态侦察的概念，分析了电子侦察卫星对雷达的侦察性能，指明了雷达反卫星侦察的一些战术技术措施。

In this paper, the general knowledge of some typical SIGINT satellites is shown from the viewpoint of information war. And, basing on the summary of the principle of electronic reconnaissance, the concepts of complete, non-complete and ill conditioned reconnoitering are respectively proposed. Therefore, the capability of the satellites to discover the various home and foreign radars is analyzed, and then radar countermeasures against SIGINT satellite are naturally pointed out as well.
