频率域解释方法,指的是利用异常的频谱特性进行反演解释的方法。异常的频谱分为振幅谱和相位谱两部分,它们是作为空间座标函数的位场的付立叶变换。在国外,异常频率域解释的研究兴起于六十年代,虽然经过了一段相对冷落的时期,但近年来又重新活跃起来。在这篇文章中,我们拟讨论以下内容:(1)频谱的计算,(2)位场频谱的基本规律,(3)规则物体异常的频谱,(4)振幅谱的解释方法,(5)相位谱的解释方法。最后我们通过一些实例来看看频率域解释方法的特点。
The method of frequency domain interpretation refers to the method of inversion interpretation using the anomalous spectral characteristics. Abnormal spectrum is divided into two parts of amplitude spectrum and phase spectrum, which are Fourier transforms of the field as a function of spatial coordinates. Abroad, the study of anomalous frequency domain interpretation rose in the 1960s, but after a period of relative neglect, it has reemerged in recent years. In this article, we intend to discuss the following: (1) spectrum calculation, (2) basic laws of the field spectrum, (3) regular object anomalies, (4) interpretation of the amplitude spectrum, (5) Phase spectrum interpretation method. Finally, we take a few examples to see the characteristics of the frequency domain interpretation method.
