Abstract : A detailed theoretical treatment of the reduction of a class of non-stationary backgrounds to stationary ones using logarithmic recievers was developed. It is shown that the logarithmic receiver will perform this function on Rayleigh-distributed background and on the output of an OR-circuit having n Rayleigh-distributed inputs. The conditions under which the logarithmic receiver is an appropirate processing device were analyzed; two sufficient conditions on the probability density function of the background are derived.
