RESUMO

Analytical expressions for computation of the signal/noise ratio at the output of the device for autocorrelation processing of frequency-modulated (FM) signals, convolving the incoming signal at the auxiliary heterodyne frequency, are obtained. The produced expressions take into account the mismatch of the carrier frequency and the width of the relative frequency spectrum and the receiver pass-band, as well as the mismatch between the beginning of signal processing and its appearance at the receiving system input.
