Chirp Rate and Instantaneous Frequency Estimation: Application to Recursive Vertical Synchrosqueezing

Résumé

This letter introduces new chirp rate and instantaneous frequency estimators designed for frequency modulated signals. These estimators are first investigated from a deterministic point of view, then compared together in terms of statistical efficiency. They are also used to design new recursive versions of the vertically synchrosqueezed short-time Fourier transform, using a previously published method. This study paves the way to the real-time computation of a time-frequency representation which is both invertible and sharply localized in frequency.
