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.

Spaceborne MIMO Synthetic Aperture Radar for Multimodal Operation [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2015
In this paper, we introduce a novel multiple-input multiple-output (MIMO) synthetic aperture radar (SAR) concept for multimodal operation. The proposed system employs waveforms based on the orthogonal frequency division multiplexing (OFDM) technique and digital beamforming (DBF) on receive.

Hurricane Monitoring With Spaceborne Synthetic Aperture Radar [PDF]

, 2017
Several TerraSAR-X and TanDEM-X ScanSAR images are acquired in October, 2012 to track the Hurricane Sandy. Three of the images are acquired in the open sea, which are presented in this chapter to demonstrate observations of sea surface wind and wave extracted from X-band ScanSAR image with high spatialresolution of 17min the hurricane.
