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。
