Application Of Communication Reconnaissance Information In Radar Network Countermeasures

The radar network system uses communication means to enable the radars in the network to realize information sharing and interconnection,which has brought huge challenges to contemporary radar electronic countermeasures.At present,most researches on the countermeasure technology of radar network are aimed at the interference of radar network system,and there are few literature on the research of radar network reconnaissance and identification.Radars are related to each other through the network,if we want to carry out an effective attack on the radar network,we must fully understand the relationship between the radars in the network.The radar netting type includes the communication and transmission relationship between the radars in the network;In addition,by analyzing the radar netting type,the criticality level of each node in the radar network can be obtained,and then the threat degree of each node can be judged,which will provide support for the selection of subsequent interference strategies and the scheduling of interference resources.In this paper,a series of research and analysis are carried out based on the recognition of the radar netting type.To identify the characteristics of the radar network system,it is necessary to fully understand the radar network system itself.This article first introduces the basic concepts of the radar network system,and uses the key mathematical model of the radar network system to model and simulate the radar network system.The difference between the radar network and the traditional radars is that in addition to all the functions of the traditional radar,the radar network alse enables the radars to communicate and share information through corresponding communication devices.Therefore,analyzing and studying the communication characteristics of the radar network is the breakthrough point for the research of the radar network countermeasures.Base on the establishment of the radar network system model,this paper fully analyzes and extracts the communication characteristics of the radar network system through different types of radar network and different simulation scenarios.The recognition of radar netting type is a kind of pattern recognition.Radar networks in different netting types have different characteristics,these characteristics will form the rules for distinguishing different netting types,by analyzing the radar networks in each types,the characteristics of different types can be extracted,and then the radar netting types can be further classify and identify.In addition,different radar network systems will have different changes in their system characteristics when facing interference,so adding the characteristics of the radar network under countermeasures will be more helpful to the recognition of the radar netting types.This paper studies and analyzes the parameter changes of the radar network system in different scenarios,and uses these features combined with the D-S evidence fusion theory to correctly identify the radar netting type.
