the analysis of the influence of non-Gaussian additive noise on the accuracy of estimates of the parameters of useful signal, carrying information about the movement of detected object located at a small distances from the radar meter was carried out. Estimation of potential accuracy of the measurement of informative signal parameters on background of non-Gaussian additive noise was obtained. Engineering estimations of the informative signal parameters on the background of additive non-Gaussian noise, with independent nature were found.
