In-situ Decametric Radar Observations of Ocean-Wave Directional Spectra during the 1974 NORPAX 'Pole' Experiment.
Abstract
Multi-frequency decametric surface-wave radar observations of ocean-wave backscatter from the R. V. Thomas Washington during the 1974 NORPAX 'Pole' experiment are described. The equipment installation, experimental techniques, and data processing are discussed. Both stationary and synthetic aperture observations were made. All of the data were obtained under low-wind conditions, usually less than 10 m/s. Stationary observations indicated a moderate amount of first-order line broadening, with the second-order continuum typically 20-30 dB below the first-order peak. Multi-wavelength synthetic aperture directional ocean-wave spectra were quite broad, typically 120-180 degrees at the half-power points, with front-to-back ratios of no more than 15 dB.
