TROPOSPHERIC REFRACTION CORRECTIONS USING A MICROWAVE RADIOMETER.
Abstract
The accuracy of radar tracking systems has increased to the stage where one of the the major limiting factors is tropospheric refraction, especially at low elevation angles. Much effort has been expended to establish realistic error models and to correlate ground measurements with refraction over the ray path. Because of the variability, both in space and in time, of the refractive index of the atmosphere, these efforts have net with only limited success. This report discusses a technique which shows promise of considerably improving this situation. (Author)
