MICROWAVE SCANNING RADIOMETER [12 records]

Record 1 2023-03-28

English

Subject field(s)
  • Weather Stations and Meteorological Instruments and Equipment
  • Remote Sensing
  • Electromagnetic Radiation
  • Spacecraft
CONT

Passive microwave radiometers can be grouped into two categories : conical scanning radiometers and cross-track scanning radiometers. A passive microwave radiometer is considered a conical scanning radiometer when the footprint size and earth incidence angle remain unchanged across the scan line, while a cross-track scanning radiometer has varying footprint size and earth incidence angle across the scan line.

OBS

Conical scanning radiometers are characterized by a continuous instrument calibration, with the sensors passing, at every rotation, below two calibration sources: a cold-sky reflector ... and an on-board calibration target (OBCT) which provides a hot temperature reference.

DEF

Instrument for measuring microwave radiation refracted by a non-smooth surface, such as the sea.

CONT

Instrumentation flown on Seasat included a radar altimeter, a microwave scatterometer for measuring surface wind speed and direction, a scanning multichannel microwave radiometer for sea surface temperature, a visible and infrared radiometer, and the first spaceborne synthetic aperture radar.

CONT

Microwave scatterometer ... measures the microwave scattering or reflective properties of surfaces. It is also non-imaging, and is specifically designed to measure backscattering. This requires that it detect more detailed spectral information than imaging radar but has reduced spatial resolution and aerial coverage. The surface is scanned in two or more directions, usually by multiple sensors. The primary application of microwave scatterometers is to measure wind vectors (that is, speed and direction) over the ocean surface. This is based on the principle of ocean ’roughness’ being caused by wind and resulting in a characteristic surface pattern which may be identified by its scattering properties.
