Abstract
The Labrador Extreme Waves Experiment (LEWEX) was an international effort to assess methods of measuring and modeling the directional aspects of wind-generated ocean waves, especially their evolution in the presence of rapidly turning winds. The author describes data-processing methods that have been developed to derive estimates of two-dimensional wave height-variance spectra from the ocean imagery obtained in LEWEX by a C-band synthetic aperture radar (SAR) system aboard a Canadian CV-580 aircraft. SAR spectra at altitudes of 20000 and 12000 ft are compared for both large ( approximately 50 degrees ) and small ( approximately 25 degrees ) radar look angles. Independence spectral estimates from both a surface contour radar and a radar ocean wave spectrometer aboard a NASA aircraft are used to verify the surface wave spectrum.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
