Fourier transform spectroscopy is an efficient method for processing spectra data obtained using interferometers. Nearly all infrared spectroscopy techniques (such as FTIR) and nuclear magnetic resonance (NMR) are based on Fourier transforms.
The second difficulty with Fourier transforms is that they use oscillatory waveforms (sine functions) as the basis functions into which the sample data is decomposed.

can occur with image processing, a technique developed in the late 1960s by NASA and the private sector to provide contrast enhancement, false colour rendering and a variety of other techniques including use of two dimensional Fourier transforms.
We recall that the PSD is the Fourier transform of the CBOC/TMBOC autocorrelation function. CBOC/TMBOC signals are formed from the convolution of PRN code waveforms, CBOC/TMBOC modulation waveforms, and navigation data (when present).
The calculations can be efficiently done from a dense terrain model applying the Fast Fourier Transformation.
