能量重心频谱校*加汉宁窗，利用离散窗谱函数的能量重心是坐标原点的原理，根据功率谱重心法则求出频率校正量，进而校正相位。-The energy center of gravity the spectrum correction with hanning window using a discrete window spectral function of the energy center of gravity is the principle of the origin of coordinates, obtain the frequency correctionunder the center of gravity of the power spectrum rules, and then correct the phase.
