Abstract. We considered the issues related to the estimation of measurement accuracy of vector information parameters of the signal, carrying the information about the motion of extended objects along with the additive uncorrelated non-Gaussian noise. It is demonstrated that taking into account the non-Gaussian nature of the actuating additive noise can significantly improve the accuracy of the estimated parameter and the greater is the difference between the probability density of the additive noise and Gaussian noise, the higher is the gain achieved. We obtained the expressions for estimating the accuracy of measurement of information parameters of the signal along with the correlated, in general, non-Gaussian additive noise. It is demonstrated that taking into account non-Gaussian nature of the additive noise can significantly improve the measurement accuracy of the information parameters.

Key words: radar meter, extended object, additive correlated non-Gaussian noise, information parameters of the signal.
