Towards the Sea Ice and Wind Measurement by a C-Band Scatterometer at Dual VV/HH Polarization: A Prospective Appraisal

Remote Sensing, 2020
Following the mission science plan of EPS/Metop-SG C-band scatterometer for 2023–2044, we consider the potential application of the sea ice/water discrimination method based on the minimum statistical distance of the measured normalized radar cross ...

Intercalibration of Backscatter Measurements among Ku-Band Scatterometers Onboard the Chinese HY-2 Satellite Constellation

Remote Sensing, 2021
The Chinese HY-2D satellite was launched on 19 May 2021, carrying a Ku-band scatterometer. Together with the operating scatterometers onboard the HY-2B and HY-2C satellites, the HY-2 series scatterometer constellation was built, constituting different ...

Evaluation and Calibration of Remotely Sensed High Winds from the HY-2B/C/D Scatterometer in Tropical Cyclones

Remote Sensing, 2022
Haiyang-2 scatterometers (HY-2A/B/C/D) have limitations in high wind speed retrieval due to the complexity of the remote sensing mechanism and the influence of rainfall on the radar cross section under the conditions of tropical cyclones.

The Scatterometer Climate Record Pathfinder [PDF]

IEEE International Geoscience and Remote Sensing Symposium, 2003
While originally designed for ocean wind measurement, radar scatterometers have proven to be very effective in monitoring land cover and ice conditions and in climate studies. The NASA Scatterometer Climate Record Pathfinder (SCP) project has generated a unique climate data record from the series of historic and ongoing scatterometer missions.

Aquarius Scatterometer Calibration

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
In this paper, we discuss the Aquarius scatterometer calibration, starting with the instrument calibration. We examine the stability of Aquarius as quantified using the loop-back power and estimated receiver gain to shown Aquarius has been extremely stable to order 0.1 dB since mission start.

A two-parameter wind speed algorithm for Ku-band altimeters [PDF]

, 2002
Globally distributed crossovers of altimeter and scatterometer observations clearly demonstrate that ocean altimeter backscatter correlates with both the near-surface wind speed and the sea state.
