An approximate method of spectral analysis called ‘successive spectral analysis’ based upon the mean-quadratic approximation of an empirical function by generalised trigonometric polynomial with both unknown frequencies and coefficients is developed. A few quotations describing some properties of the method as well as one of the possible methods for numerical solution are given.

Further development and properties of the spectral analysis by least-squares
The concept of spectral analysis using least-squares is further developed to remove any undesired influence on the spectrum. The influence of such a ‘systematic noise’ can be eliminated without the…

TLDR
The principles of windowed leastsquares spectral analysis are explained as an alternative method of the Least-Squares Spectral Analysis in order to access a time-frequency representation of irregularly sampled GRACE range rate time series related to Iran’s main catchments.
Antileakage least-squares spectral analysis for seismic data regularization and random noise attenuation
Spatial transformation of irregularly sampled data series to regularly sampled data series is a challenging problem in many areas such as seismology. The classical Fourier analysis is limited to…
Spectral Estimation from Irregularly Spaced Data
Observational data often is irregularly taken or has large gaps due to instrument failure or other real world effects. Yet no spectral estimation theory in use allows one, without dubious…
