Signal detection against the background of non Gaussian clutter from underlying surface

The method for the operating characteristics of the radio systems estimation based on using of model of non Gaussian clutter from underlying surface (sea, land plots) is proposed. The method use half Markov combined processes. The parameters of parametric (Neumann - Pearson, adaptive control of threshold and filter of selection stopband) and non-parametric (sign and linear rank) detectors are analyzed. The loss value of signal to noise ratio is appeared owing to non Gaussian of clutter parameters is estimated.
