ACOUSTIC SIGNAL DETECTION BY SIMPLE CORRELATORS IN THE PRESENCE OF NONGAUSSIAN NOISE. I. SIGNAL TO NOISE RATIOS AND CANONICAL FORMS

Abstract

The detection of underwater acoustic signals by simple auto- and cross-correlation receivers in the presence of non-normal, as well as normal background noise is examined on the basis of signal-to-noise ratios calculated from a generalized deflection criterion. Particular attention is devoted to the effects of impulse noise and mixtures of impulse and normal noise on system performance. Comparisons between system behavior vis-a-vis the 2 types of interference are made. For impulse noise equivalent in spectral distribution and av intensity to a gauss noise background, it is found that the output signal-to-noise (power) ratios are related by a canonical expression.
