  针对存在的缺点,本文提出了一种应用于激光多普勒测速的高精度信号处理技术,即首先利用加hanning窗的welch修正周期图算法得到信号功率谱,搜索其谱峰值频率,接着利用goertzel频谱细化算法对搜索的谱峰进行细化分析,再引入能量重心频谱校正算法对细化后的谱峰进行校正分析,从而将离散频谱分析算法、频谱细化算法和频谱校正算法三者有机结合起来,充分发挥各自的优点:通过加hanning窗的welch修正周期图算法快速得到功率谱及峰值频率,通过goertzel算法获得分析频带的高分辨率频谱,然后通过能量重心校正算法对细化后的频谱进行高精度校正,这样不仅保证了算法的高效性,而且大大提高了分析的精度。
