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。
The Pulse Doppler (PD) radar signal processing system mentioned in this paper is composed of a speed tracking loop and a digital signal processing auxiliary channel. The system uses a number of signal processing techniques and successfully solves the technical problems of signal detection and tracking, interference identification and countermeasures at low signal-to-noise ratio. The paper elaborates the design idea and gives some simulation and test results.
