Application And Implementation Of The Radiation Source Location Location Based On The Space Electromagnetic Environment

With the development of electronic and communication technology,the use of wireless electronic products is becoming more and more popular.Concomitant unknown radiation source and interference radiation sources are also more and more,these unknown radiation sources and radiation interference source will cause great interference to normal information communication,affect the normal communication quality,even further by spreading false and garbage information to personal or economic purposes.Especially in the population of the city,this effect is more prominent.Therefore,it is directly related to the quality of the normal communication network that the acquisition of these unknown sources and the geographical position of the source of interference,and then take measures to eliminate the impact of these malicious or unwanted radiation source to normal communication.In addition,the results of the visualization of the 3D electromagnetic environment prediction system can provide primary data and very useful reference for the spatial localization of the radiation source.So it is important to study the spatial location of the radiation source.In this paper,a method for the development and implementation of a radiation source location system based on the electromagnetic radiation distribution is presented.Among them,the distribution of the electromagnetic radiation prediction platform is mainly responsible for theprediction of the electromagnetic situation in the virtual reality environment.The radiation source location system is based on the analysis and calculation of the predicted results of the electromagnetic distribution,and then the distribution of the space position of the radiation source is obtained.OpenGL is used as the graphics library and DEM(Elevation Model,Delegate Model ITM)to construct the virtual reality space environment.Based on the above,the ray tracing model,Irrigular(Terrian)model and the ITU-RP.1238 model are used to forecast the electromagnetic environment.According to the results of the electromagnetic radiation distribution system,the radiation source location system is analyzed by using the particle swarm algorithm and the hierarchical model.The development of the above two systems are based on the OpenGL graphics library,using MFC C++ as the development framework.Among them,the radiation source positioning system also uses the.NetFrameWork3.5 and some COM components as a programming basis.In this paper,we have accumulated a certain technical foundation and experience in engineering practice for the prediction of the electromagnetic situation and the spatial position of the radiation source.The realization of the electromagnetic radiation distribution forecast system and the radiation source location system can be used as the basis for the communication network planning and military battlefield command.
