CROSS-TRACK SCANNING RADIOMETER [2 records]

Record 1 2023-03-28

  • 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.
