A scatterometer for monitoring the performance degradation of an infrared instrument in the Diffuse Infrared Background Experiment (DIRBE) due to contamination of the primary mirror is described. The scatterometer monitors the scattered light from an off-axis internal source to provide a measure of the integrity of the optical system.

Satelliten-scatterometer zur windmessung
Acta Astronautica, 1984Zusammenfassung Fur die Wettervorhersage uber dem Festland ist die Kenntnis der Wetterverhaltnisse uber den Meeren von entscheidender Bedeutung. Das Skylab S-193-Experiment sowie SEASAT haben gezeigt, das eine weltweite Windmessung uber den Meeren mit Hilfe eines Mikrowellensensors technisch moglich ist.

Automated high-speed Mueller matrix scatterometer
Applied Optics, 1997A new scatterometer-polarimeter is described. It measures the angular distribution of intensity and of the complete Mueller matrix of light scattered by rough surfaces and particle suspensions. The measurement time is 1 s/scattering angle in the present configuration but can be reduced to a few milliseconds with modified electronics.

Seasat scatterometer observations of sea ice
IEEE Transactions on Geoscience and Remote Sensing, 1999Seasat I scatterometer data collected over the Beaufort Sea are analyzed and compared with a simple theoretical model that includes surface roughness and volume scattering. The values of the root-mean-square (rms) surface slope of roughness and the volume scattering albedo are adjusted to fit the data.

Multiband-scatterometer data analysis of forests
International Journal of Remote Sensing, 1987Abstract The airborne multiband scatterometer DUTSCAT promises to become a useful tool for research in the field of active microwave remote sensing. The system can measure accurate σ ° values in six frequency bands simultaneously at a selected incidence angle and polarization.
