In this paper, the application of maximum likelihood estimation (MLE) to evaluate the parameters of the Doppler spectrum (DS) signal, which is a mixture of reflections from the target and the clutters, is considered. The choice of MLE is justified taking into account the limited sampling of the input data. The derivation of the optimum algorithm for estimating the parameters of the DS in accordance with its chosen parametric model is derived from the maximum likelihood criterion. To get rid of the procedure for estimating non-informative parameters, we used design matrices and obtained an expression for the final objective function (OF), the result of optimization of which is to obtain DS parameter estimates. The problem of optimizing the multidimensional and multimodal FT obtained as a result of MMP is solved.
