Modeling and Simulationic of Electron Reconnaissance Satellite's Information Acquisition and Processing

电子侦察卫星是空间对地目标侦察的主要力量,可对地面雷达和通信信号进行侦测和定位。文章分析了电子侦察卫星的有效载荷雷达信号接收机侦察性能,利用随机理论、航天动力学原理和模糊匹配方法,建立了三类模型:信息源模型、信息获取模型和信息处理模型,用来进行雷达目标的产生、卫星的星下点、覆盖带计算、点的包含性检验、目标定位和目标类型判断。结合目标特性和电子侦察卫星侦察原理,设计了仿真流程,并对仿真结果进行了分析,针对其被动侦察的特性,给出了基本的对抗策略。

Electronic reconnaissance satellite is the main force for ground reconnaissance from space. This paper analyzes the reconnaissance capability of radar signal receiver. Based on random theory , space dynamic theory and fuzzy theory, this paper sets up three kinds of models：information source models, information acquiring models and information processing models. Those models can produce radar targets,calculate the sub - satellite point and overlay area,check up coverage of spot,ascertain target＇s orientation and types. Then it designed simulation process, analyzed the result of simulation and gave the basic countermeasure strategy.
