摘要
介绍了一种功能完备的雷达数字中频接收机,其具有数字中频处理,数字定相,发射脉冲频谱分析及功率校正,AFC控制等功能。其可用于常规磁控管雷达多普勒改造或提升模拟中频相参多普勒系统性能,也适用于全相参系统接收机中频数字化改造或进一步的性能提升。采用该数字接收机,典型磁控管整机系统的改善因子限制可达40dB以上。该数字接收机性能高,集成度高,适用性广。
In this paper, a multi-functional digital IF receiver for radar system is introduced. The functions of the IF receiver include IF processing, digital phase locking, transmit burst spectrum analysis, echo power correction, AFC control, etc. It is suitable for the Doppler upgrading of radars using magnetron and for the performance improvement of analog coherent-on-receive systems, as well as for the promotion and performance maximization of klystron system.
