Implementation And Study In Electromagnetic Environment Simulation System Calculation Module Based On Dynamic Ray Tracing Algorithm

With the rapid development of information technology, electronic war becomes a new form of combat in modern war. Both sides in the war for the electromagnetic power competition is increasingly fierce. Electronic information equipment is widely used in modern battlefield; it forms the complex battlefield electromagnetic environment. The complex battlefield electromagnetic environment simulation has become a key point in the research of modern military field. However, there are many shortcomings in the existing electromagnetic environment simulation software, both efficiency and usage scenarios are unable to meet the battlefield environment on the electromagnetic simulation computation. To solve these problems this paper studies a set of electromagnetic environment simulation system based on dynamic ray tracing algorithm of calculation module, and through the idea of distributed computing, further improving the overall electromagnetic environment simulation system of the simulation efficiency.The main purpose of this paper is to improve the simulation speed in complex electromagnetic environment. Firstly ray tracing method—the core algorithm of electromagnetic environment simulation system calculates module was introduced in detail. This paper analyzes the deficiency of existing algorithms on the efficiency, thus to improve the efficiency of the algorithm is dynamic ray tracing algorithm is proposed. And introduces in detail the dynamic ray tracing algorithm thought and the core data structure of the algorithm. After the macro analysis of the core algorithm, the article also discussed from the point of view of micro electromagnetic environment simulation calculation formula of electromagnetic parameters in the process and receiver of magnetic situational simulation model in detail in this paper.Secondly this paper introduced in detail in other accelerated method besides calculation module. In view of this topic adopts the multithreaded programming and distributed processing has carried on the detailed introduction. This paper gives the architecture and the core design thought of parallel computing technology. Then it analyzes in the process of parallel computing to overcome difficulties, and the corresponding solutions.
