高逼真回波数据源和一体化仿真流程是相控阵机载预警雷达技术研究的重要保证,可以真实全面地满足技术验证的需求。文中将相控阵机载预警雷达系统零中频回波数据的高逼真产生至后端的信号处理和数据处理整套流程仿真,分为外部环境模块和内部处理模块进行了研究,通过仿真过程比较了模块中各节点输出信号与参数的理论计算结果,以及最终的数据处理输出与想定设计,验证了仿真系统的逼真性和一体化特征。

High-fidelity echo data source and integrative simulation procedure are important guarantee for the study on phased-array airborne early warning (AEW) radar, which can satisfy the requirement for technical identification more really and entirely. Being divided into external environment module and internal processing module, the total simulation procedure from producing zero intermediate frequency echo data realistically for phased-array AEW radar system to signal processing and the data processing is discussed. The output signals from all the nodes in modules are compared with the parameters theoretical arithmetic results and the final data processing output is compared with the scenario design, which proves the fidelity and integration of the simulation system.
