clouddrift.wavelet.morse_properties

clouddrift.wavelet.morse_properties(gamma: ndarray | float, beta: ndarray | float) → tuple[ndarray, ndarray, ndarray] | tuple[float, float, float]

Calculate the properties of the demodulated generalized Morse wavelets. See Lilly and Olhede (2009), doi: 10.1109/TSP.2008.2007607.

Parameters

gammanp.ndarray or float

Gamma parameter of the wavelets.

betanp.ndarray or float

Beta parameter of the wavelets.

Returns

widthnp.ndarray or float

Dimensionless time-domain window width of the wavelets.

skewnp.ndarray or float

Imaginary part of normalized third moment of the time-domain demodulate, or ‘demodulate skewness’.

kurtnp.ndarray or float

Normalized fourth moment of the time-domain demodulate, or ‘demodulate kurtosis’.
