Abstract
This paper considers problems related to measuring the information parameters of the processed signal reflected from the located object under additive non-Gaussian correlated noise. It is shown that in the case of exposure to non-Gaussian correlated noise, an increase in the correlation coefficient promotes the growth in the generalized signal/noise ratio, which, in turn, improves the accuracy of measurement of the signal parameters. These dependences confirm that the measurement error of the information parameters of the signal is affected not only the generalized signal/noise ratio, but also by accounting for the non-Gaussian nature of the additive noise, which leads to a significant improvement in the accuracy of measurement of these parameters.
