Аннотация: Abstract: A statistical study of the effectiveness of the non-threshold search procedure for a noise-like phase-shift keyed signal by the delay time is carried out during observation against the background of noise and single-tone continuous wave interference for various options for its frequency position. The formation of the output effect of the search procedure due to the transition to the frequency domain using the discrete Fourier transform is considered. Families of dependences of the probability of correct search performance on the dimensionless frequency detuning are obtained for various “interference/signal” (jam-to-signal) ratios. A significant variation of the permissible level of energy superiority of interference over the signal is shown at which the value of the selected quality indicator is preserved. Quantitative and qualitative conclusions are made about the effect of single-tone continuous wave interference on the efficiency of the non-threshold search procedure. © 2022, Pleiades Publishing, Inc.
