Due to existing signal processing technology ’ s shortage such aslow measurement, narrow measurement range precision and other poor performance, we introduced a high - precise signal processing technology : firstly, to get power spectrum with hanning windowed welch modified periodogram, search its peak value frequency ; secondly, to apply zooming analysis via goertzel algorithm ; at last, to get a highly precise doppler frequency with energy centrobaric rectifying algorithm 。 the simulating result indicated that this technology introduced could get accurate doppler frequency 。 depending on above discussed technology, we designed a signal processing scheme, and developed a signal processing system. the running result showed high performance, verified the feasibility and reliability of the highly precise signal processing technology introduced. in a word, the technology improved ldv ’ s performance such as measurement precision, measurement range, dynamic response time 。 and it will have a wide application foreground
針對存在的缺點,本文提出了一種應用於激光多普勒測速的高精度信號處理技術,即首先利用加hanning窗的welch修正周期圖演算法得到信號功率譜,搜索其譜峰值頻率,接著利用goertzel頻譜細化演算法對搜索的譜峰進行細化分析,再引入能量重心頻譜校正演算法對細化后的譜峰進行校正分析,從而將離散頻譜分析演算法、頻譜細化演算法和頻譜校正演算法三者有機結合起來,充分發揮各自的優點:通過加hanning窗的welch修正周期圖演算法快速得到功率譜及峰值頻率,通過goertzel演算法獲得分析頻帶的高解析度頻譜,然後通過能量重心校正演算法對細化后的頻譜進行高精度校正,這樣不僅保證了演算法的高效性,而且大大提高了分析的精度。Methods for determination of fibre length by comb sorter diagram
