On clutter modeling and the spectra of two-dimensional Gauss-Markov random signals
Abstract
The spectral properties of two-dimensional isotropic clutter signals are examined for the cases in which (1) the clutter has an exponential spatial autocorrelation function, and (2) the clutter is a two-dimensional Gauss-Markov random signal. The one- and two-dimensional power spectral densities before and after antenna filtering are obtained, and some of the differences and similarities between these two models are discussed in the context of spectral analysis.
