AN ANALYSIS OF THE CORRECTION OF RANGE ERRORS DUE TO ATMOSPHERIC REFRACTION BY MICROWAVE RADIOMETRIC TECHNIQUES.

Abstract

The accuracy of systems which measure range to missiles or satellites is limited by atmospheric refraction. The MARCOR technique corrects for range errors due to the wet component of atmospheric refraction by using thermal emission measurements in the vicinity of the water vapor resonant line at 22.235 GHz. These measurements are made by a radiometer pointing in the approximate direction of the tracked object, and related to the line integral of the wet refractivity. The effects of various simulated measurement and approximation errors on the accuracy of the final result are analyzed statistically for Miami, Florida, meteorological profiles. The MARCOR results are compared with methods which have been used. (Author)
