摘　　要：为解决雷达发射信号的监测问题,提高发射信号的稳定性,在普通雷达发射机的技术基础上,提出了一种雷达发射机反馈系统设计,该反馈系统采用外差式结构,可对发射信号实时监测,并将其转换成探测脉冲信号送入雷达发射机前端,与发射机一起构成闭环控制系统,大大提高了发射系统的稳定性;应用结果表明,该检测系统运行稳定可靠,检测精度高,具有一定的实用性和推广价值。To solve the radar transmit signal monitoring problems and improve the stability of the transmitted signal,presenting a radar transmitter feedback system design based on the traditional radar transmitter.The feedback system uses heterodyne RF structure,realtime monitors the transmitted signals,and converts it to a probe pulse signal into the front of the radar transmitter.The feedback system constitutes the closed-loop control system with the transmitter together,which greatly improves the stability of the transmission system. The application shows that this system runs stably and accurately.The technology and methods adopted in the system are practical and worthy of using abroad.
