摘要：

The high-resolution Doppler imager (HRDI) on the Upper Atmosphere Research Satellite is a remote sensing instrument used to observe winds in the Earth's stratosphere, mesosphere, and lower thermosphere. Winds are measured by determining the Doppler shift of emission (mesosphere and lower thermosphere) and absorption (stratosphere) lines of the O-2 atmospheric (b (1) Sigma(g)(+)-X (3) Sigma(g)(-)) band. The HRDI is a triple-etalon Fabry-Perot interferometer with a resolution of approximate to 0.05 cm(-1) and very good white-light rejection. Careful design and calibration has limited systematic errors in the wind determination to less than 5 m/s.
