高速高精度锁相倍频跟踪滤波器

Phase-locked frequency-doubling tracing filter of the hing speed and high precision

本文介绍了锁相倍频跟踪滤波器的组成及工作原理,提出了提高多普勒信号捕获速度及解决跟踪失锁问题的措施。为激光技术在机械制造中的应用提供了有效的信号处理手段.

In this paper, the composition and working principle of the phase-looked frequency-doubling tracing filter have been lntraduced. Posing some methords for raising the capture speed of the doppler signal and for settleng the problem of the frequency tracking lock-out as well as. Those provide one efficient means of the signal processing for Laser technical application in manufacturing.
