A key point in Short Time Fourier Transform is the choice of window function. Although rectangle window is regarded as the first choice because it's featured by integral harmonic to filter signals and by DC component, decaying DC component and frequency shift of signals cause great error to rectangle window STFT. In addition, transient signals contain rich information of faults, but the fixed time window of STFT fail to collect these information.
STFT 算法关键问题之一是窗函数的选择,矩形窗以滤除信号整数次谐波和直流分量的特点自然称为首选窗,但衰减直流分量和信号的频率偏移对矩形窗 STFT 造成了很大误差;其次,暂态信号中含有丰富的故障信息,傅立叶变换固定的频窗忽略了这些特征信息。

In sphere approximate, GPS/Gravity-BVP is Neumann problem over exterior spherical domains. Then the natural boundary reduction, suggested by Feng and Yu, is applied to deal with the three dimensional problems. By expansion in spherical harmonics, the natural integral equations of harmonic problems over exterior spherical domains are obtained. Meanwhile, a numerical method for solving geodetic BVP is developed.
