Airborne Wind Vector Scatterometer for Sea Surface Measurements

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2019
This paper describes the development of an Airborne Wind Vector Scatterometer for low-resolution wind speed measurements. The scatterometer is designed to meet a wind speed accuracy requirement of 1 m/s. In this ad hoc and low-budget project, the development of the instrument exploited some already existing subsystems.

Implementation of Pulse Compression on an Airborne Scatterometer

IGARSS 2008 - 2008 IEEE International Geoscience and Remote Sensing Symposium, 2008
The pulse compression scheme implemented on the Imaging Wind and Rain Airborne Profiler (IWRAP) is described. Developed at the UMASS Microwave Remote Sensing Laboratory (MIRSL), IWRAP is a dual-band (C and Ku) conically scanning Doppler scatterometer designed to map the atmospheric boundary layer wind fields, ocean surface wind fields, and ...

The DUT Airborne Scatterometer

International Journal of Remote Sensing, 1987
Abstract An airborne scatterometer system operating at six frequencies simultaneously between 1 and 18 GHz has been developed for the measurement of the microwave scattering of vegetation, forests, sea and other targets. After a description of the instrument, some C- and L-band results are presented.

Calibration of the CCRS airborne scatterometers

IEEE Transactions on Antennas and Propagation, 1990
A series of experiments and associated analyses which were designed to lead to an end-to-end calibration of the Canada Centre for Remote Sensing (CCRS) fanbeam scatterometers are described. The method followed was originally introduced in 1984 by A. Yizhar et al. for the Ku-band scatterometer at one incidence angle.

Data Processing and Calibration for an Airborne Scatterometer

IEEE Transactions on Geoscience and Remote Sensing, 1986
The ERASME radar system has been designed to be easily mounted on small helicopters or aircraft. As it is used for research investigations on radar remote-sensing applications, it has to be well calibrated in every configuration, both absolutely and relatively for comparisons at different points of the swath.

Airborne Microwave Rain-Scatterometer /Radiometer

International Journal of Remote Sensing, 1982
Abstract An airborne microwave rain-scatterometer/radiometer system operated at 10 and 34-45 GHz was developed for the remote sensing of precipitation, especially rain, from an aeroplane. Airborne rain-scatterometers were developed as a first step for the development of the future spaceborne rain-scatterometer.
