dc.description This paper shows that the scale domain appears to be the appropriate domain for bat signal analysis. (The most recent upgrade of the original software package that calculates Time-Frequency Distributions and Instantaneous Frequency estimators can be downloaded from the web site: www.time-frequency.net. This was the first software developed in the field, and it was first released publicly in 1987 at the 1st ISSPA conference held in Brisbane, Australia., and then continuously updated). en_US
dc.description.abstract Scale domain signal analysis has been developed in response to the need to analyse Doppler-tolerant waveforms or self-similar random signals. Following Cohen's concept of scale representations, this paper introduces the concept of higher-order scale-spectra and investigates advantages and drawbacks of scale domain versus the traditional frequency domain analysis. Several scale-domain methods are applied to a natural signal (a bat echolocation pulse) including the scale spectrum, the scale bispectrum and a smoothed Q time-scale distribution. en_US
