Analysis of Tropospheric Effects at Low Elevation Angles

1978
Abstract : Precision low elevation angle radar observations of orbiting spheres were used to evaluate the utility of surface based refraction techniques. Elevation angle error measurements were obtained from differences between the precision radar measurements and the true or absolute position of the orbiting sphere obtained from a multiple pass orbit ...
