Abstract: A dual-polarized, coherent, X-band microwave radar called RiverRad was deployed at the Coastal Engineering Field Research Facility at Duck, NC in April, 2008. The purpose of the deployment was to utilize this calibrated radar to calibrate a marine radar operated by Oregon State University (OSU) on a long-term basis at Duck and to study microwave backscatter in the surf zone. Data from RiverRad were compared with those from the marine radar and with imagery from several video systems also deployed at Duck by OSU on a long-term basis. Besides providing accurate calibration of the marine radar, RiverRad data also showed that HH polarized backscatter from the surf zone is frequently equal to or larger than that of VV when averaged over several minutes. Scattering from whitecaps was studied using a volume scattering model and found to produce HH and VV backscatter at nearly equal levels. The origin of the high HH values is still under investigation.
