Algorithm and software design of radar reconnaissance environment

以离散时间仿真原理为基础,研究了雷达侦察信号环境的数学模型和仿真算法,并对雷达脉冲参数进行了建模和分析。考虑到雷达侦察信号环境的复杂性,引入了噪声干扰脉冲和脉冲丢失处理。软件设计过程中,采用了结构化功能模块设计,菜单式操作方法,可以在线修改需要产生的雷达种类、雷达部数和各部雷达的参数,可以按时域生成各种体制的雷达脉冲描述字数据表、所有雷达脉冲交错后的脉冲描述字数据表和所有雷达的参数设置记录表,并输出到相应的文件。该仿真软件所仿真的信号可以用于进行雷达信号分选识别研究。经分析验证,该软件设计合理,生成数据可靠。

Based on the theory of discrete time events simulation, mathematic model and simulation algorithm of radar reconnaissance environment are studied, and parameters of radar pulse are modeled and analyzed. As radar reconnaissance environment is very complex, noise interfering pulse and pulse missing process are introduced. In the software design, structured module design is introduced, which adopts menu operation method, and users can randomly modify the radar parameters, choose radar types and radar number on-line. The software can produce radar PDW data files and parameters recording files. Application in actual cases shows the design of the software is reasonable, and the data produced is reliable.
