针对通信对抗系统干扰压制能力问题，在干扰方程的基础上，提出基于干通比的干扰压制区分析方法。该方法通过考虑战术运用的地理环境，分析通信链路、干扰链路的传播模型，推导2种传播模型的干扰方程。将干通比引入干扰方程后，建立干扰压制区方程，根据干通比的大小关系，讨论不同情况下的干扰压制区。结合对超短波电台、无人机数据链干扰的典型通信对抗场景开展干扰压制区分析。基于干通比的通信对抗系统干扰压制区分析方法，能够具象化描述干扰压制区和干扰无效区，对于指导通信对抗战术运用效果明显。

Aiming at the problem of jamming suppression capability of communication countermeasure system, on the basis of jamming equation, a jamming suppression area analysis method based on jamming-to-communication maximum distance ratio is proposed.By considering the geographical environment of tactical application, this method analyzes the propagation model of the communication and jamming link, and derives the jamming equations of two propagation models.After jamming-to-communication maximum distance ratio being introduced into the jamming equation, the equation of jamming suppression area is established.According to the size relationship of the jamming-to-communication maximum distance ratio, this paper discusses the jamming suppression area in different situations, combining with the typical communication countermeasure scenarios of ultra-short wave radio station and unmanned aerial vehicle(UAV) data link jamming, carries out the jamming suppression area analysis.The jamming suppression area analysis method of communication countermeasure system based on jamming-to-communication maximum distance ratio can figuratively describes the jamming suppression area and jamming invalid area, which is effective in guiding the tactics application of communication countermeasure.
