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 文章首先對(duì)跳頻通信的基本理論做出了一定的闡述,并對(duì)目前跳頻通信技術(shù)的發(fā)展給跳頻干擾帶來(lái)的困難做出了一定的分析。
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 摘要在介紹地形跟隨回避雷達(dá)工作原理的基礎(chǔ)上,通過(guò)設(shè)定典型超低空突防飛機(jī)的戰(zhàn)術(shù)行動(dòng),分析了對(duì)雷達(dá)實(shí)施有效干擾所必須具備的條件,包括偵察干擾機(jī)的部署、數(shù)量要求等;并計(jì)算了在傳感器擺放(投擲)式干擾機(jī)模式下對(duì)裝備的性能要求,得出了在目前技術(shù)條件下,對(duì)地形跟隨回避雷達(dá)實(shí)施干擾在技術(shù)和戰(zhàn)術(shù)上都是困難的。
