Measurement of Sea Scatter and Buoy Tracks at Long Ranges by High- Resolution OTH-B Radar

Abstract

This is the final report on a two-year contract entitled 'Measurement of Sea Scatter and Buoy Tracks at Long Ranges by High-Resolution OTH-B Radar.' The Wide Aperture Research Facility (WARF), a high-resolution skywave high- frequency (HF) radar located in central California, was used to obtain remote measurements of the ocean wave spectrum, overwater wind velocity, and ocean currents in the North Pacific Ocean. The ocean currents were determined by tracking drogued and undrogued drifting buoys carrying a low-power HF repeater. Three types of sea backscatter Doppler spectra were recorded to determine the ocean wave spectrum and the wind velocity: (1) Backscatter from wide areas of the ocean to develop techniques for mapping wind fields, (2) Backscatter from limited areas near research vessels, Navy ships, and ships of opportunity to correlate the observed and radar-measured wind field; (3) Long-term coherent samples of backscatter for high-resolution off-line processing to derive the ocean wave spectrum.
