On Measurement of the Sea Surface Wind Vector by the Airborne Weather Radars Having a Various Scanning Sector
نویسندگان
چکیده
A method for estimating the near-surface wind vector over water using the airborne weather radar in addition to its standard navigational application is discussed. A case of an airplane rectilinear flight over the water surface is considered. The radar operates in the ground-mapping mode in the range of middle incidence angles as a scatterometer. Wind vector is recovered from the azimuth normalized radar cross section data obtained from a scanning sector. Algorithms for extracting the wind speed and direction are proposed.

Microwave Measurement of the Wind Vector over Sea by Airborne Radars
The oceans of the Earth work in concert with the atmosphere to control and regulate the environment. Fed by the sun, the interaction of land, ocean, and atmosphere produces the phenomenon of weather and climate. Only in the past half-century meteorologists have begun to understand weather patterns well enough to produce relatively accurate, although limited, forecasts of future weather patterns...

Monopulse radarsare one of the most accurate tracking radars used to guide various platforms. Detection and tracking of surface targets with these radars are performed in order to point strike targets. Sea clutter presents challenges for detecting floated targets and in addition to affecting detection height, it can cause errors in monopulse angle finding. In this paper, the airborne monopulse ...

The rise of satellite altimetry is a revolution in the ocean sciences. Due to its global coverage and its high resolution, altimetry classically outperforms in situ water level measurement. Ekman and geostrophic currents are large parts of the ocean’s current, playing a vital role in global climate variations. According to the classic oceanography, Ekman and geostrophic currents can be calculat...

Active microwave radar satellites transmit and receive radar signals with wavelengths in the range of centimeters to one meter thus measuring the roughness of the sea surface, which enables the retrieval of wind and ocean wave fields. Synthetic Aperture Radars (SAR) are capable of imaging synoptic wind fields with a coverage of up to 500 km x 500 km and a resolution of down to 100 m. As the rad...
