摘　　要：针对高分辨力雷达扩展目标回波模拟,文中设计并实现了一种高分辨力雷达扩展目标模拟系统。建立了一维距离像目标、二维面目标、三维体目标的目标回波模型,结合宽带射频接收机技术、大瞬时带宽基带回波信号产生技术、目标RCS(Radar Cross Section)数据获取与调制技术以及宽带捷变频率合成器等关键技术完成了高分辨力雷达扩展目标模拟系统的设计与实现。使用该系统对某典型战斗机目标进行了射频仿真和二维成像处理,并将射频仿真和二维成像处理结果与使用RadBase仿真软件对该典型战斗机目标的仿真结果进行对比,验证了该系统的有效性。验证结果表明,该系统的射频仿真二维成像处理结果和RadBase仿真软件的仿真结果基本一致。This study presents the design and implementation of a high-resolution radar extended target simulation system for simulating extended target echoes in high-resolution radar.The study establishes target echo models for one-dimensional distance targets,two-dimensional surface targets,and three-dimensional volume targets.The key technologies used to achieve the design and implementation of the high-resolution radar extended target simulation system include wideband RF receiver technology,large instantaneous bandwidth baseband echo signal generation technology,target RCS(Radar Cross Section)data acquisition and modulation technology,and wideband agile frequency synthesizer.The system is used to conduct RF simulation and two-dimensional imaging processing of a typical fighter jet target,and the results are compared with the simulation results obtained using RadBase simulation software to verify the effectiveness of the system.The validation results indicate that the RF simulation and two-dimensional imaging processing results of the system are consistent with the simulation results obtained using the RadBase software.
