摘要
将重磁异常相位谱主值换算到0～2π范围,依据相邻两点相让谱主值之差决定相位谱真值的校正项,达到相位谱复位。
This paper deals with the properties of the phase spectra of gra-vity and magnetic anomalies and proposes a new method to restore thetrue spectrum from discrete phase spectrum. By using the restoring me-thod, the principal value of discrete phase spectrum is converted into 0～2π from -π/2～+π/2, and the restoring correction value is determinedaccording to the difference between two neighbouring principal valuesto rcstore true phase spectrum.
