Abstract :
A recent evaluation of algorithms for determining RMS wave heights from the spectral structure of HF ocean surface radars has shown that a fast and accurate analysis is available. This algorithm is used to discover how spatial and temporal measurements of significant wave heights compare with in situ measurements. Temporal autocorrelations have the same time scales as synoptic meteorology and spatial correlations are consistent with bathymetric scales. It is shown that HF radar Doppler spectra can be used effectively for mapping significant wave heights in coastal seas, where bottom topography induces changes in wave heights, within the scale of the mapping capability of about 20 km
