Abstract : Apparatus and method for discriminating against non-Gaussian noise. Analog signala from an array of sensors are converted to real and imaginary digital representations and processed such that non-Gaussian noise is separated from signals of interest. The processor uses estimates of Kurtosis and quantiles from either past or adjacent frequency components to construct non-linear elements, which are then used to process remaining signal data to improve the signal-to-noise ration thereof by removing non-Gaussian noise therefrom.
