Dual-beam interferometry for ocean surface current vector mapping
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2001-02-28)
Article
Accés obertThe recent use of along-track interferometry (ATI) in synthetic aperture radar (SAR) has shown promise for synoptic measurement of ocean surface currents. ATI-SARs have been used to estimate wave fields, currents, and ... -
Extension of Kirchhoff method under stationary phase approximation to determination of polarimetric thermal emission from the sea
(IEE-INST ELEC ENG, 1998-07-31)
Article
Accés obertWind direction over the sea can be determined from radiometric measurements of the third Stokes parameter (TU). The Kirchhoff method is extended under the stationary phase approximation to compute the dependence of TU on ... -
The processing of hexagonally sampled signals with standard rectangular techniques: application to 2D large aperture synthesis interferometric radiometers
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1997-01-31)
Article
Accés obertIn Earth observation programs there is a need of passive low frequency (L-band) measurements to monitor soil moisture and ocean salinity with high spatial resolution 10-20 km, a radiometric resolution of 1 K and a revisit ...
