| Description | |
| Abstract | Main objectives of ADI'DAS have been:
-to investigate the physical mechanisms that give rise to different appearances and properties of signatures of oceanic phenomena (like internal waves in the ocean) and atmospheric phenomena (like internal waves and convective cells in the marine atmospheric boundary layer) in microwave radar images of the ocean at horizontal (HH) and vertical (VV) polarization;
-to develop a comprehensive numerical model which is capable of reproducing observed radar signatures of oceanic and atmospheric features and their dependencies on radar frequency, incidence angle, and, in particular, polarization;
-to determine the sensitivity of radar signatures to parameter variations and, in particular, characteristic differences between signatures of oceanic and atmospheric phenomena in dual-polarization radar imagery, which can be exploited for the development of advanced automatic feature detection and classification algorithms;
-to develop and demonstrate an automatic detection and classification algorithm for signatures of oceanic and atmospheric features in radar images of the ocean, and to investigate the capabilities and limitations of such algorithms.
This work is particularly relevant for the interpretation of data from the ASAR system on ENVISAT, which has the capability to acquire dual-polarization (HH and VV) synthetic aperture radar imagery.
Some scientific / technological developments within ADI'DAS were expected to be relevant for a wide range of investigations and applications besides the automatic detection of radar signatures of oceanic and atmospheric phenomena.This way, the ADI'DAS project was expected to provide significant contributions to a better interpretation of radar images of the ocean and the development of advanced remote sensing / monitoring systems, as well as to a better understanding of interaction processes and fluxes at the air-sea interface and in the marine atmospheric boundary layer.
The improved radar imaging model components and data interpretation algorithms developed within ADI'DAS are clearly superior to models and algorithms which were available at the beginning of the project. This will have a significant impact on many activities dealing with the interpretation of radar signatures of oceanic phenomena and of atmospheric phenomena over the ocean. In particular, an automatic discrimination between radar signatures of oceanic and atmospheric origin is expected to have very positive impacts in research-oriented and operational oceanography. |
