Research Of Electronic Warfare Simulation System Based On SystemVue

Message is playing a very important role in modern wars,and the platforms of information wars have been developed from land,sea or air to outer space.Electronic warfare,which is a significant component of modern information wars,intercepts enemy's signal to obtain information or disable enemy's communication system by reconnaissance and interfence.Electronic warfare system carried on satellite can monitor a bigger area than other traditional systems,and can work continuously in a specific area or moving fast around the earth.Also satellite platform won't be affected by surface geographical conditions or laws,which makes satellite electronic warfare system working freely.Compared with other traditional system,satellite electronic warfare system costs much more,which makes verifying system by simulation methods important when we don't have unlimited resources.This thesis studies simulation of satellite electronic warfare system and the mainly works are:1.To meet the needs of reusable designation,method of splitting electronic systems in electronic warfare scene into models by function is proposed.And the method of realization of reusable models in new simulation platform is firstly proposed and the realization is firstly realized.the simulation system designed in this thesis achieve the effect of combining suitable models to build desired electronic system and warfare simulation scene.2.Four kinds of typical digital communication modulation was studied and the algorithm was proposed to solve the problem of non-cooperation signal reconnaissance.The methods of estimating frequency by zero-crossing property and bandwidth by Welch transform are also proposed.Simulation results show those methods are effective in communication reconnaissance.3.To avoid operating complicated simulation software directly and meeting the needs of transferring data and files to overall platform,development of visual software for the simulation system using CSharp is studied and finished,the visual software is able to launch and set parameters for simulation,show results,processing data and transferring data to overall platform.The simulation system studied in this thesis is a part of a pre-research project and is deployed and tested.The results certificate the correction of this system.
