摘　　要：针对某型相控阵雷达目标模拟器采用单目标技术,无法真实模拟跟踪多目标回波信号的问题,设计了一种新型多目标模拟器。该模拟器采用DDS(Direct Digital Synthesis,直接数字频综)信号产生、数字信号存储及控制等技术,结合航迹数据产生与控制软件,实现多目标回波信号模拟的同时,实现并完善了模拟器的多目标引导数据注入、理论弹道演练和实测数据回放等模拟和训练功能。软件部分,在考虑目标回波特性的基础上,利用施威林Ⅰ型模型产生目标回波,实现目标回波的模拟仿真工作。在硬件上设计了以FPGA(Field Programmable Gate Array,现场可编程门阵列)为核心的功能模块,将模拟仿真信号实时生成目标回波。实际应用表明,该模拟器控制简单,运行稳定,精度高,完全满足跟踪测量和模拟训练需求。As the target simulator for a phased array radar uses single-target technology and can not simulate multi-target echo signals, a new multi-target simulator is designed. Based on DDS （Direct Digital Synthesis） technology and DSP （Digital Signal Processor） technology as well as control software, the multi-target simulator realizes multi-target echo signal simulation. It also realizes and improves guidance data injection, theory trajectory drilling and measured data playback. In the software, taking into consideration the characteristics of target echo, echoes are generated on Swerling I model to complete target echo simulation. As for the hardware, a functional module is designed to create target echo from simulation signals based on FPGA （Field Programmable Gate Array） . Tests and appIications show that the simulator has a high stability in operation with a high accuracy with simplified control, meeting all requirements of target tracking and simulation and training.
