抄録

An effective method is proposed for the estimation of instantaneous frequency of signals which are observed corrupted by random noise. The method is based on the idea of maximum likelihood function constructed indirectly from the Wigner distribution of the observation data. The effectiveness of the method is confirmed by simulation experiments.
