Spectral analysis of magnetic anomalies due to a 2-D horizontal circular cylinder : a hartley transforms technique

الملخص EN

The spectral analysis of the vertical effect of magnetic anomalies due to a 2-D horizontal circular cylinder is presented using Hartley transform.

Hartley transform is an alternative approach to the famous complex Fourier transform.

The depth to the center of the horizontal cylinder can be computed by a simple equation as a function of frequency.

A synthetic example has been used to illustrate this technique and the validity of this approach has been proved by applying it to real data of a narrow band of quartz-magnetite in Mangampalli near Karimnagar town, India.

The noise analyses were tested on the technique and showed a high level of confidence.

The results of the field example are in good agreement with the ones published in the literature.
