Evaluation Of Communication Interference Effect In Tactical Radio Network

Tactical Internet,as an omni directional tactical communication system for network centric warfare,is used to transmit command and control information and situational awareness information.Tactical Internet mainly includes grid backbone network and network form,rich tactical radio internet.The tactical radio internet,tactical radio network(referred to as Tactical Radio Network,TRN)can quickly adapt to the change of mobile warfare module,survivability performance is the main means of communication the basic combat unit under the condition of information technology is an important operation of communication countermeasure in.Based on the research of military tactical radio network,network construction by using the simulation software,based on the analysis of the routing protocol,mobile model,analyzed the network performance,and study the evaluation of communication jamming effectiveness for tactical radio network.In this paper,the grey analytic hierarchy process(AHP)is used to evaluate the communication jamming effectiveness,and the evaluation method of communication jamming effectiveness based on rough set and cloud model is proposed,and the simulation calculation and comparative analysis are carried out.The main work of the paper is as follows:(1)Introducing the related knowledge of Tactical Internet,drawing out the concept of tactical radio network,and analyzing the development and current situation of the effect evaluation.(2)Network construction and performance analysis.First,study the composition analysis of typical tactical radio network structure,construction of tactical radio network by OPNET simulation software;secondly,comparative analysis of on-demand routing protocol and the AODV table driven DSDV protocol;third,comparative study of mobility model in random waypoint mobility model(RWP)and mobile group mobility model(reference point RPGM);finally,analyze the tactical radio network performance index system from the tactical level and operational level,and the establishment of communication jamming effectiveness evaluation index system,through the performance analysis to prove the feasibility of the simulation network.(3)Using the grey analytic hierarchy process to study the communication jamming effect.First of all,the network simulation to obtain the performance curve before and after interference based on data processing,get the evaluation sample matrix;secondly,using AHP,construct judgment matrix and the calculation of the maximum eigenvalue,determined the index weight;third,according to gray theory,construct the whitenization weight function,calculating the gray weight matrix,the effect evaluation.(4)The evaluation method of rough set and cloud model is proposed to study the communication jamming effect.First of all,the distribution function based on rough set reduction communication jamming effectiveness evaluation index system;secondly,the combination of rough sets and conditional information entropy theory,analysis about the index weight;finally,based on the cloud model,build cloud generator,calculate the weighted deviation,effect evaluation.(5)Constructing communication jamming effect evaluation system.The interference effect of tactical radio network is convenient for users.
