A step-by-step procedure is outlined to convert synthetic aperture radar imagery into estimates of ocean surface-wave spectra. The procedure is based on a linearized version of a model that relates synthetic aperture radar image intensity spectra and wave slope- or height-variance spectra. The outlined procedure is applied to synthetic aperture radar imagery from the Shuttle Imaging Radar mission and is shown to produce spectra that, except in the lowest sea state, are highly correlated with two-dimensional spectra measured independently.
