基于DSP和FPGA的多雷达脉冲信号模拟器设计

Design of Multiple Kind Radar Pulse Signal Simulator Based on DSP and FPGA

主要介绍了一种基于PC＋DSP＋FPGA体系结构的多雷达脉冲信号模拟器，能够模拟1—4部常规雷达、重频抖动雷达、重频参差雷达、重频参差抖动雷达、频率捷变雷达等多种体制雷达的混叠脉冲信号，并提供对应的载频编码输出，仿真度高。雷达的部数及每部雷达的参数可通过主控计算机中的主控软件进行设置，使用方便灵活，信号通用性强。该系统可在电子战设备前端微波分系统不参与的条件下，为后级数据处理分系统调试提供逼真的雷达测试信号。

A multiple kind radar pulse signal simulator based on PC ＋ DSP ＋ FPGA system is introduced in this paper. This simulator can simulate interleaved pulse signals of 1 - 4 kinds of radars, including PRF jittering radar, PRF staggering radar, PRF staggering jittering radar and frequency agility radar, etc. It also provides output of carrier frequency code correspondingly. The number and parameters of radars can be set in the control software on the PC. Therefore, this system has the advantages of flexibility and universalness. This system can provide realistic radar test signals for debugging secondary data processing subsystem when the electronic warfare equipment is not possessed of microwave subsystem.
