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。Applied study of gps antenna used in fuze
