相位分析法 meaning in Chinese

phase method

This way can also be used to self - verify by the controller . phase analysis and unwrapped arithmetic are introduced here in detail
同时针对散斑图像的条纹相位分析法介绍了移相技术和去包裹算法。
By 1 - d fourier transform , we could analyze wave spectrum and get wave speed by computing phrase shift , then calculate the velocity of the wind , so we can avoid the problem of " sub - pixel motion "
使用傅立叶相位分析法，对示踪云进行频域波谱分析，由谐波的相位变化计算波速，继而得出风速，能够避免“亚像素尺度位移”问题，提高导风的精确度。
2 - d fourier technique could compute horizontal and vertical speed of cloud motion in the same time , so it can avoid the error caused by 1 - d moving supposition in the 1 - d fourier technique . in this part , the 2 - d fourier technique theory was introduced , and a numerical simulation was given in this paper . in the third part , we compared the 2 - d fourier technique with the 1 - d fourier technique , analyzed their problems and found ways to resolve them
用二维傅立叶相位分析法导风，同时计算水平和垂直方向的风速，能够避免一维傅立叶相位法导风中一维平移假设带来的误差，文中介绍了二维傅立叶相位法导风的基本理论和风速计算方法，并给出二维傅立叶导风技术的数值实验。
