Abstract :
The performance of the synthetic aperture radar (SAR) aboard the Russian ALMAZ-1 and the European ERS-1 satellites for imaging ocean surface waves is investigated. Collocated ALMAZ-1 and ERS-1 SAR images were acquired quasi-simultaneously on Oct. 6 and Oct. 8, 1992, over the North Atlantic in the vicinity of the island of Iceland. The SAR image spectra calculated from the ALMAZ-1 and ERS-1 images are compared with simulated SAR image spectra which are obtained from a wave spectrum hindcast by the WAM wave prediction model
