Sar Electronic Warfare Applications Of Real-time Visual Simulation Technology

With the continuous development of computer and simulation technology, applications of virtual reality technology in the military field become more pervasive. A large number of foreign scholars conduct their research on three-dimensional visual simulation(which is an important branch of of virtual reality technology), and have made lots of achievements and developed a wide range of application requirements. Moreover, the modeling of the electronic confrontation sysem is mostly related to a variety of weapon platforms regarding electronic information confrontation, the increasingly complex battlefield, large-scale mathematical models, and numerous input and output data. While the simulation method based on traditional structure is very abstract and analytical, the complex mathematical formulas and vast amounts of data are very hard for people to understand except modeling and simulation personnel. Under this specila situation, according to the demand of electronic countermeasures simulation training and electronic confrontation assessment, research on real-time electronic confrontationand visual simulation technology are extremely important.This dissertation does a detailed research on the real needs of the SAR electronic countermeasures simulation, and has done a deep investigation and study on the international mainstream of the current real-time visual simulation technology. Combined with the advantages of various real-time visual simulation systems, and with the real needs of electronic countermeasures simulation, a set of SAR real-time visual simulation of electronic combat systems was designed by the author.The system solved the key technical issues on the SAR electronic countermeasures real-time visual simulation systems, such as the system software design, data interfaces, large scene models and scenario-driven, SAR against the effects of electronic performance software implementation, and also the use of HLA distributed simulation technology is designed and implemented on realizing the SAR ECM Real-time visual simulation software. This system got good result on practicing and implicating, providing a simulation platform for the SAR the effectiveness of electronic countermeasure.The innovative contributions of the dissertation to this field are as follows: (1)As for the project of real-time computervision emulation of SAR electronic warfare, I have designed and carried out a real-time computervision emulation system, providing an emulational and real-time exhibition platform for the accurate evaluation of the outfit of SAR electronic warfare.(2)As for the real-time dispatching problem in big settings, I have designed and carried out an algorithm which tunes in the big settings with fractional steps, solving the real-time bottleneck problems of ordinary computers will encounter when running on the setting with large quantities of data.(3)For the requirement of real-time computervision emulation, I have studied and realized the special effects of computervision emulation and real-time driving technique. The final applicance proves that the real-timing and performance of the system is good, which provide certain experience to use for reference for the practice of real-time computervision emulation and theoretical innovation.(4)Applying theory for practice, I have studied and applied various key techniques about HLA, accumulating experience for the development of emulational software of electronic warfare.
