摘要：
The Ingara X-band fully polarimetric medium-grazing-angle sea-clutter data set was collected in the Australian maritime environment over an angular range of 360 degrees in azimuth and from 15 degrees to 45 degrees in grazing. This paper reports further analysis of this data set, focusing on understanding the azimuth variation to enable improved simulation accuracy and extraction of relevant geophysical parameters. This includes some original properties of the co-and cross-polarized normalized radar cross section as a function of the scattering geometry and sea surface parameters. We also assess the performances and limitations of recent sea surface scattering models in the light of this rich data set.
