Investigation of Low-grazing-angle Microwave Backscattering from Three- Dimensional Breaking Sea Waves
The microwave backscattering of the sea surface is investigated with the wedge-shaped breaking waves for the super events at low grazing angles (LGA). According to the relationship between the wave breaking and the whitecap, the finite three-dimensional wedges are utilized to approximately model the breaking waves, of which the spatial distribution is simulated with whitecap coverage. The phase...
متن کاملModelling low grazing angle electromagnetic scattering from the sea surface
We review the integral equation (IE) description of low grazing angle scattering of microwaves, in the main by extended corrugated structures modelling the sea surface and accounting for their effectively infinite extent through the adjunct plane (AP) construction. Solution of the discretised IE by an iterative scheme that incorporates an improved method for the evaluation of the AP contributio...
متن کاملModeling of Microwave Backscattering from a Rough Sea Surface with Steep Waves
Traditionally, Kuand C-band radars are used in ocean scatterometry to retrieve an ocean wind vector. Examples are QuikSCAT and ASCAT satellites. Recently, attempts have been made to use X-band SAR aboard the German TerraSAR-X satellite for the same purpose [1]. Usually, wind retrieval is performed using empirical Geophysical Model Functions (GMF). In the past, a set of GMFs have been designed b...
متن کاملBreaking wave contribution to low grazing angle radar backscatter from the ocean surface
[1] The anomaly of radar sea spikes, defined here as the non-Bragg scattering events with backscattering cross-section of horizontal polarization exceeding that of the vertical polarization, has been associated with steep wave features possibly going through wavebreaking process, with or without whitecap manifestation. This property is exploited for using a dual polarized radar as a remote sens...
متن کاملHigh Grazing Angle Sea-Clutter Literature Review
This report reviews the published literature on the characteristics of mono-static radar seaclutter observed with high grazing angles (typically above about 10). To date, most of the analysis and modelling of sea-clutter has been undertaken at low grazing angles with the main application being for surface and airborne maritime radars. The report identifies some of the data sets that have been ...
