Birth-death Model and Characters Creating Models of Complex Electromagnetic Environment

复杂电磁环境主要由各类辐射源辐射的电磁信号交互作用而产生。应用随机理论,建立了辐射源的生灭过程模型,采用蒙特卡洛方法动态仿真辐射源状态;建立了给定目标点的有效辐射源筛选、功率密度计算和辐射脉冲流密度计算模型;给出了仿真流程。满足电磁环境仿真的适应性、动态性和实时性需求。

Complex electromagnetic environment comes from many different radiations and their interaction. A birth-death model of radiant points was built on the stochastic theory, and then the states of radiant points were dynamically simulated by Monte Carlo. Some characters creating models were built, including model of filtering valid radiant points, model of power density computing and model of pulse steam density computing. Finally, a simulation process was proposed. All of those have met electromagnetic environment simulation requirement in adaptability, dynamic and real-time.
