Electromagnetic wave is an important medium and the best carrier for information acquisition,transmission,using and confrontation in the battlefield,but the complex environment will have a great impact on the transmission of electromagnetic waves.Compared with traditional test methods,virtual tests have lower test costs and shorter cycles.Therefore,the purpose of this project is to develop an electromagnetic wave signal transmission calculation module based on the self-developed virtual environment platform.The purpose of the project is to develop an electromagnetic wave signal transmission calculation module so as to promote the application of H-JTP platform in equipment joint test under assumed complex environmental.First of all,this thesis studies the key technologies of electromagnetic wave transmission effect calculation in complex environment.It studies the influence of different media parameters on electromagnetic wave signal transmission.It also applies S3 DRG three-dimensional region growing algorithm and AABB bounding box representation method which are used to quantize and represent complex environments.In this thesis,the intersection of signal transmission path and boundary environment recognition method and the different representation methods of signal transmission path are studied,and the complete transmission path is divided into small segments as a way input for electromagnetic wave transmission effect calculation.A high-performance transmission effect calculation service method combining with multi-core parallel and multi-node distribution is proposed,which can improve the calculation efficiency of transmission effect.Based on the research of key technologies,the electromagnetic wave signal transmission module was designed and developed with accordance of the needs of virtual experiments for the calculation of electromagnetic wave signal transmission effects,and the universal interface of the electromagnetic wave transmission model was designed to achieve versatility and scalability.In this project,MODTRAN,a medium-resolution atmospheric radiation transmission mode,was selected as the electromagnetic wave transmission model.Therefore,the MODTRAN is called based on MODTRAN API application program interface.The object-oriented way adopted,UML modeling language is used to describe the software design and development process.After analyzing the software functional requirements,designing the software static model,dynamic model and user interface,QT and Visual Studio platform is used to develop the software.Finally,the calculation method verification of electromagnetic wave transmission effect and the software test of electromagnetic wave signal transmission module under complex environment are completed.The test results show that the electromagnetic wave signal module developed in this project can call the electromagnetic wave transmission model normally and quantize the complex environment correctly and properly identify the intersection of the signal transmission path and the environment.
