摘要
为满足二次雷达射频脉冲时序测试需求,设计研制了一种二次雷达射频脉冲信号时序记录系统。通过主控器完成对各模块通讯、协同控制、数据融合与记录;设计了专门AD采集模块,集成了FPGA处理、信号放大、AD转换、GPS等模块,可实现信号滤波放大,特征判断,加注时间戳等功能;通过对信号特征进行设置筛选,可实现对目标信号进行值守式记录存储,节省了大量的存储空间。测试表明,该系统记录数据速度快、时序精度高、对目标信号截获概率大,具有一定的应用前景。
In order to meet the requirements of secondary radar RF pulse timing test,a timing recording system of secondary radar RF pulse signal is designed and developed.Through the main controller to complete the communication,collaborative control,data fusion and recording of each module;designed a special AD acquisition module,integrated FPGA processing,signal amplification,AD conversion,GPS and other modules,which can realize the functions of signal filtering and amplification,feature judgment,time stamping,etc.;by setting and screening the signal characteristics,the target signal can be recorded and stored in“on duty”mode,which saves a lot of storage space.The test results show that the system has the advantages of fast data recording speed,high timing accuracy and high probability of intercepting target signal,which has a certain application prospect.
