Towards Radar Imaging of Ocean Phenomena
نویسندگان
چکیده
A model of radar imaging of ocean phenomena is proposed. This model is an extension of the background NRCS model [7] in the case of non-uniform medium. Radar scattering component takes into account Bragg and non-Bragg (specular reflections and impact of wave breaking) scattering mechanisms. Varying surface current, surface temperature and surfactants are the main sources of medium non-uniformities. Transformation of wave spectrum and wave breaking in non-uniform medium is described in the relaxation approximation. Model calculations are compared with field observations. An overall good agreement is obtained. It is shown that wave breaking play important role in the formation of radar signatures of ocean phenomena.

The paper focuses on the occurrence and development of coherent structures observed in the atmosphere above ocean under natural conditions. Microwave imaging radars are suggested as data take instruments. The phenomena of marine atmospheric cells and rolls onset, horizontal planform, aspect ratio and scaling phenomena are examined. Convective patterns manifested in radar images and information ...

Introduction: Understanding the relationship between ocean surface waves and the radar backscatter they generate is key to the development of new radar-based techniques to measure ocean parameters, such as wave height and current speed and direction, of importance to both the Navy and the civilian sector. This knowledge is also needed to improve the Navy’s ability to distinguish between signals...
