Noise filtering in a variational wind field retrieval from Doppler radar

Meteorologische Zeitschrift, 2001
Two different concepts for noise filtering in a DOPPLER radar wind field retrieval are compared. The first technique is a smoothing on the raw radar data. The second method uses a smoothness constraint within a variational technique in which a model wind

Study on the Elimination Method of Wind Field Influence in Retrieving a Sea Surface Current Field

Sensors, 2022
An along-the-track interferometric synthetic aperture radar (ATI-SAR) system can estimate the radial velocity of a moving target on the ground and on a sea surface current.

Enhanced Wind-Field Detection Using an Adaptive Noise-Reduction Peak-Retrieval (ANRPR) Algorithm for Coherent Doppler Lidar

Atmosphere, 2023
Wind fields provide direct power for exchanging energy and matter in the atmosphere. All-fiber coherent Doppler lidar is a powerful tool for detecting boundary-layer wind fields.

Doppler radar wind field retrieval over the Po Valley [PDF]

Natural Hazards and Earth System Sciences, 2006
Although methods of using multiple Doppler radars to study wind fields have long been proposed, and many research studies have been made, very few operational radar operators adopt methods which require the use of specific scanning strategies to allow ...

A Review for Retrieving Wind Fields by Spaceborne Synthetic Aperture Radar [PDF]

Journal of Sensors, 2022
A high-resolution sea surface wind field (SSWF) has high application requirements, such as weather forecast, wind energy evaluation, and oil spill monitoring. The models for retrieving SSWFs based on spaceborne synthetic aperture radar (SAR) are important methods for obtaining high-resolution SSWFs.

Bayesian inference for wind field retrieval [PDF]

Neurocomputing, 2000
In many problems in spatial statistics it is necessary to infer a global problem solution by combining local models. A principled approach to this problem is to develop a global probabilistic model for the relationships between local variables and to use this as the prior in a Bayesian inference procedure.
