Some Skywave Radar Measurements of Wind Vectors and Wave Spectra
Observations of ocean backscatter spectra were made with a skywave radar during the Joint Air Sea Interaction (JASIN) Experiment in July and August 1978. This chapter is concerned with a detailed analysis of the results from four days of the experiment, July 20–21 and August 7–8, and with a comparison of radar-derived ocean parameters (sea surface wind vectors and nondimensional wave spectra) with equivalent parameters determined by conventional ship and buoy instruments. Because of the ionospheric propagation mode employed, contamination of the radar return signal due to ionospheric motions causes some degradation of radar Doppler spectra and radar-derived ocean parameters. In general, however, mean agreement to within 10% for all parameters except wave spectra was found over the four days, while the radar-derived surface wind fields fitted well to the mesoscale flows determined by conventional meteorological analysis.
