The algorithm of signal detection against noises of the big intensity with various laws of allocation is offered. Research and estimation of characteristics of detection on the basis of mathematical modeling of the searcher of a signal with casual amplitude and an initial phase against pulse interferences and noises with probability exponential distribution is conducted. It is shown that for poor signal detection it is necessary to make two non-linear operations over each accepted sampling, correlative accumulation (product and summation) results of these operations coordinated with expected samplings of a signal and their squares, module calculation.
