傅立叶方法提供了一个特别优美的框架，从它发展出一种描述成象的方法。 - In the first part , we introduced 1 - d fourier technique to calculate the velocity of the wind , and analyzed the error in tracking cloud motion by 1 - d fourier technique
第一部分，给出一维傅立叶相位法导风的理论及其平移假设所带来的误差。 - 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。 - 1 - d fourier technique is based on 1 - d moving supposition , but cloud motion is not only horizontal but also vertical , so the error would come into existence . the error in tracking cloud motion by 1 - d fourier technique was analyzed . in the second part , 2 - d fourier technique was put forward
一维傅立叶相位法基于一维平移假设，而实际上风既有水平方向的速度又有垂直方向的速度，即一维平移假设不能满足，文中指出一维傅立叶相位法导风中由于一维平移假设所带来的误差。
