Abstract

A nonparametric method for time-frequency localization of broadband signal energy is developed on the basis of optimization problem solution with the l2-norm as the objective function. The method is effective in significant a priori uncertainty conditions and improves the performance of classical spatial spectral analysis methods and high-resolution methods.
