Optimization of frequency-time localization of a priori unknown broadband signals

摘要

A nonparametric method of frequency-time localization of the energy of a priori unknown broadband signals is obtained by a solution of an optimization problem with objective function in the form of an l_2 norm. The method is based on radio-holographic processing in antenna arrays, a technique that increases the efficiency of the classical methods of spatial spectral analysis and high-resolution methods.
