摘要
在雷达电磁环境仿真系统中,需要模拟生成描述雷达信号环境的脉冲描述字(PDW)数据,以引导系统生成干扰信号环境数据。采用PDW对雷达信号环境进行描述,结合雷达信号环境的PDW数学模型,给出了基于PDW的模型框架,并设计了雷达电磁环境仿真流程。最后归纳了生成PDW数据的处理方法,给出了载频、重频和脉宽的模拟生成示例。
In the simulation system of radar electromagnetic environment, simulation and generation data of PDW which describes radar signal environment is needed to guides the simulation system to generate the jamming signal data. The radar signal environment is described by PDW. According to PDW math models of radar signal environment, model structure based on PDW is presented and system composing simulation flow of radar electromagnetic environment simulation is given. Finally,the handling methods of simulation PDW data are concluded and the simulation example of ratio frequency （RF）, pulse width （PW）, pulse repetition interval （PRI） are presented.
