Abstract
An efficient method of frequency-time localization of the energy of complex unknown-shape signals is developed on the basis of solving an optimization problem with the objective function in the form of the l2 norm. The method is based on estimating the mutual-correlation level of the complex amplitude-phase distributions recovered with different resolutions in the analyzed frequency-time domain. Under conditions of single-and multipath propagation of waves, the values of the signal-localization effectiveness are compared on the basis of simulation modeling results.
