cogpy.wave.kw_spectrum

Wavenumber–frequency (k–ω) spectral analysis.

Estimates the 3-D power spectrum S(kx, ky, f) of gridded spatiotemporal signals using windowed FFTs.

Functions

kw_peaks(spectrum[, n_peaks])	Extract dominant peaks from a k–ω spectrum.
kw_spectrum_3d(data, geometry, *[, nperseg, ...])	Compute the 3-D wavenumber–frequency power spectrum.
