摘　　要：雷达仿真技术是雷达研发过程中验证测试的重要手段。本文基于Matlab/Simulink设计构建了一部较为完整的中频信号级数字阵列雷达仿真系统,能够对雷达的信号产生、阵列收发模型、信号处理数据处理、波束调度、显控终端进行仿真。本文通过仿真一部S波段数字阵雷达详细介绍了仿真系统架构设计和各模块的工作原理。本文以面向对象的思想编写仿真系统的Simulink组件和显控终端实现基于数据流Simulink雷达仿真和仿真数据的实时显示,使得仿真系统的运行速度更快,更易维护,扩展性更强。最后本文给出一个仿真实例,通过对比仿真结果和理论精度表明本系统目标探测精度在误差范围内,验证了该系统运行的正确性。该系统的实现能够给雷达设计的验证测试提供参考,为未来仿真系统的扩展奠定了基础。Radar simulation technology is an important way of verification and testing during the radar research and development process.Based on the Matlab/Simulink design,this paper builds a relatively complete intermediate frequency signal-level digital array radar simulation system,which can simulate the radar signal generation,array transceiver model,signal processing,data processing,beam scheduling,and display control terminal.This article introduces in detail the architecture design of the simulation system and the operating principle of each module by simulating an S-band digital array radar.In this paper,the Simulink components of the simulation system and the display control terminal are coded with an object-oriented idea to realize the real-time display of the Simulink radar simulation and simulation data based on the data stream,which makes the simulation system faster to operate,easier to maintain,and more scalable.Finally,this paper gives a simulation example.By comparing the simulation results and theoretical accuracy,it shows that the target detection accuracy of the system is within the error range,which verifies the correctness of the system′s operation.The realization of this system can provide a reference for the verification test of radar design and lay a foundation for the expansion of the simulation system in the future.
