Analysis of Coherent Microwave Data Collected on the Ocean Over Two Decades
Abstract
The objective of this project was to perform further analysis of data sets that had been collected over the past two decades. To this end the following data sets were further analyzed: the Airship data sets of 1993 and 1995, the SHOWEX data set of 1999, the NLIWI data set of 2005-2007, the Philippine data set of 2007, the Duck data set of 2008, and the Ship Guidance data set of 2008. Findings include, but are not limited to, the following: 1) VV backscatter agrees well with the multiscale composite surface model, 2) Breaking waves contribute more to HH than VV backscatter and can cause cross sections at HH to exceed those at VV in disagreement with composite surface theory, 3) Shadowing is not a factor in low-grazing-angle backscatter from the ocean, especially at VV polarization, and 4) Linear features in wavenumber-frequency spectra of ocean backscatter are primarily due to short gravity waves breaking at maxima of dominant-wave interference patterns.
