Validation of SAR ocean wave measurements: ERS-1 and CV-580 cross spectra, and CV-580 along-track InSAR

In December 1994 a field program, now known as Sea Truth and Remote Sensing (STARS'94), was carried out over the Grand Banks of Newfoundland. The field program has provided data which offers the opportunity to validate synthetic aperture radar (SAR) measurements of the ocean wave spectrum. The authors present validation of SAR spectral inversions, starting from the inter-look cross spectrum, for ERS-1 SAR and the CCRS CV-580 SAR. They also present a direct measurement of the heave spectrum using the along-track interferometry (ATIn-SAR) mode of the CCRS SAR.
