Abstract: The described method of increasing the sensitivity of the detection of short periodic signals in Gaussian noise based on separation of the additive mixture of signal and noise into fragments using a time window. The obtained function of the spectral values a universal criterion for the detection of the number of sections separating the studied time array. Introduced the efficiency factor of the window a spectral-statistical method to determine the optimal number of segments separating an additive mixture of signal and noise necessary for successful signal detection.

Keywords: spectral-statistical window method, detection signal in noise.
