Optimal windows for the time-frequency analysis of arbitrary swept frequency signals

Abstract

An arbitrary swept frequency signal approximated locally by a linearized frequency sweep is presented. It is shown that an optimal time window is inversely proportional to the square root of the instantaneous rate of change of frequency. The constant bandwidth of the Short Time Fourier Transform and the constant percent bandwidth of the wavelet transform represent extreme cases.
