In this paper , the fundamental theory of frequency hopping communication is introduced first , and some problems met in the electron reconnaissance with the progress of frequency hopping communication are introduced at the beginning 文章首先对跳频通信的基本理论做出了一定的阐述,并对目前跳频通信技术的发展给跳频干扰带来的困难做出了一定的分析。
On the basis of introducing the principle of the tf / ar radar , this paper analyzes the conditions of effectively jamming the tf / ar radar in typical tactical act of hedgehopping , which include the disposition and quantity of electron reconnaissance / jammer , calculates the capability request of equipments in the method of sensor / hand - emplaced jammer , and concludes that it is difficult to jam tf / ar radar at the present time 摘要在介绍地形跟随回避雷达工作原理的基础上,通过设定典型超低空突防飞机的战术行动,分析了对雷达实施有效干扰所必须具备的条件,包括侦察干扰机的部署、数量要求等;并计算了在传感器摆放(投掷)式干扰机模式下对装备的性能要求,得出了在目前技术条件下,对地形跟随回避雷达实施干扰在技术和战术上都是困难的。
