Ocean wind fields retrieved from radar‐image sequences

H Dankert, J Horstmann… - Journal of Geophysical …, 2003 - Wiley Online Library
The dependency of radar backscatter on the surface wind field is investigated using a
nautical X‐band radar operating at grazing incidence and horizontal polarization in transmit
and receive. This resulted in development of an algorithm for wind retrieval from nautical
radar image sequences. The algorithm consists of two parts: In the first part, wind directions
are extracted from wind‐induced streaks that are in line with the mean surface wind
direction. These streaks are visible in the temporal integrated radar images at scales …

Ocean wind fields retrieved from radar-image sequences

H Dankert, J Horstmann, W Koch… - … and Remote Sensing …, 2002 - ieeexplore.ieee.org
An algorithm is presented for retrieving wind vectors from radar-image sequences acquired
by a standard nautical radar near at near grazing incidence. The radar operates at X-band
(9.5 GHz) with horizontal and vertical polarization in transmit and receive. The algorithm
consists of two parts, one for wind direction and another for wind speed retrieval. Wind
directions are locally extracted from wind induced streaks, which are approximately in line
with the mean wind direction. The algorithm assumes wind direction as normal to the …
