Cross Calibration of the OceanSAT -2 Scatterometer With QuikSCAT Scatterometer Using Natural Terrestrial Targets

IEEE Transactions on Geoscience and Remote Sensing, 2014
The accuracy of ocean surface wind vectors measured by satellite-borne scatterometers depends on measured backscattering coefficient (σ°). Hence, an in-flight calibration of a satellite scatterometer is essential as this is not guaranteed by its prelaunch absolute calibration.

Cross-calibration experiment of JPL AIRSAR and truck-mounted polarimetric scatterometer

IEEE Transactions on Geoscience and Remote Sensing, 1994
When point calibration targets are used to calibrate a SAR image, the calibration accuracy is governed by two major factors. The first factor stems from the stringent requirement on the radar cross section (RCS) of the point calibration target. To reduce the effect of radar return from the background, the RCS of a point calibration target must be much ...

Calibration and Cross Validation of Global Ocean Wind Speed Based on Scatterometer Observations

Journal of Atmospheric and Oceanic Technology, 2020
AbstractGlobal ocean wind speed observed from seven different scatterometers, namely, ERS-1, ERS-2, QuikSCAT, MetOp-A, OceanSat-2, MetOp-B, and Rapid Scatterometer (RapidScat) were calibrated against National Data Buoy Center (NDBC) data to form a consistent long-term database of wind speed and direction. Each scatterometer was calibrated independently

Radiometric cross-calibration of spaceborne scatterometers: first results

SPIE Proceedings, 2009
The main application of a scatterometer is the determination of the wind speed and direction at the sea surface. This is achieved by measuring the radar backscattering coefficient in three different directions and inverting these measurements using a geophysical model function (GMF). The scientific value of the data is directly related to the quality

Cross-calibration of ERS-1 and ERS-2 wind scatterometers; Towards a homogeneous 20-year-long wind vector monitoring of the earth

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The importance of long-term, continuous, and homogenous time-series of satellite data is widely accepted and strongly fostered by the international scientific community. The various global projects and initiatives undertaken in the last few years are evidences of that effort.
