Two-Parameter Quadratic Chirplet
- Two-parameter quadratic chirplet is a signal analysis tool that models non-stationary chirp signals with quadratic phase variation.
- It refines instantaneous time-frequency analysis by integrating amplitude and curvature adjustments for improved chirp parameter estimation.
- This method supports applications in radar, bioacoustics, and communications by offering enhanced resolution compared to conventional techniques.
