A description is given of the algorithm for demodulating a linearly frequency-modulated signal against a background of white Gaussian noise with a constant component. The functions of complete sufficient statistics for estimating the phase and amplitude parameters of the signal, as well as the level of the constant component and the noise variance are found. The demodulation algorithm is implemented in the LabVIEW program environment. Computer modeling showed the asymptotic efficiency of the received estimates of the signal parameters.
