WebSep 3, 2024 · It is based on choosing the spectrum that corresponds to the most random (i.e. unpredictable) time series whose covariance function coincides with the known values (Burg 1975 ). It comes out that the solution to choosing the maximum entropy spectrum is equal to the autoregressive estimator of the power spectrum. WebAbstract: The power spectrum estimation plays a signiﬁcant role in the marine monitoring and the quality of spectrum will seriously affect the results of marine monitoring. There have been various algorithms on power spectrum estimation, one of which is Burg algorithm. Though this method can effectively improve the resolution WebMarple' s technique is useful for high resolution 2-D spectral analysis applications (like spotlight-mode synthetic aperture radar (SAR) imagery) In this thesis, 2-D extension of the 1-D Burg algoritm, developed by Marple, will be studied.
