Analysis of RADARSAT\u20102 (R2) quad\u2010polarization (quad\u2010pol) data with collocated in situ ocean wind measurements reveals that the de\u2010pol radar backscatter does not saturate in high winds. This is a significant development for radar wind sensing, because wind retrieval with copolarized (co\u2010pol) backscatter suffers from problems of incidence\u2010and\u2010azimuth\u2010angle\u2010dependent signal saturation and dampening in high winds. We present a study comparing satellite quad\u2010pol measurements with the composite surface Bragg (CB) theory of radar backscattering from the ocean surface. The co\u2010pol data are in good agreement with the CB theory. De\u2010pol data are more sensitive to wind speed compared to theoretical prediction, thus retrieval of high winds is more accurate using the de\u2010pol return. The cubic wind speed dependence of de\u2010pol returns in high winds reflects the significant breaking wave contributions. The relationship can be used to obtain wave\u2010breaking properties from space.<\/jats:p>","DOI":"10.1029\/2009jc005995","type":"journal-article","created":{"date-parts":[[2010,8,18]],"date-time":"2010-08-18T20:00:37Z","timestamp":1282161637000},"source":"Crossref","is-referenced-by-count":82,"title":["Comparison of composite Bragg theory and quad\u2010polarization radar backscatter from RADARSAT\u20102: With applications to wave breaking and high wind retrieval"],"prefix":"10.1029","volume":"115","author":[{"given":"Paul A.","family":"Hwang","sequence":"first","affiliation":[{"name":"Remote Sensing Division Naval Research Laboratory  Washington D.
