-
摘要: 本文听述及的脉冲多普勒(PD)雷达信号处理系统,主要由速度跟踪环和数字信号处理辅助通道组成。该系统综合运用了多项信号处理技术,成功地解决了在低信噪比条件下的信号检测和跟踪、干扰识别和对抗等技术问题。文中阐述了设计思想,交给出了部分仿真和测试结果。Abstract: This paper discribes a signal processing system in a Pulse Doppler (PD) radar. It mainly consists of a velocity tracking loop and a digital signal processing auxiliary channel. With many signal processing techniques, the system sucess-fully resolves the signal detection and tracking at low SNR and the interference identification and rejection. The idea of system design is introduced in details. Finally, some simulation and expreimental results are presented.
