i am trying to calculate depth to basement by using 1D fft, on this Power spectrum equation is slope divided by 4pi. it is correct or not for calculating slope of the energy spectrum.
Yes, we report the local slope of the power spectrum over 4pi as this is the conventional way to estimate the depth of a set of sources that are statistically represented in the data (as per the early work of Spector and Grant, 1970, http://library.seg.org/doi/abs/10.1190/1.1440092).
Note that there are many assumptions that must be true for this value to be useful, and you will find a number of useful discussion articles in the SEG Digital Library.0
