Preliminary study of satellite multipath interference characteristics

R. H. Ott; J. E. Herman

Abstract: The effects of multipath arising when a signal transmitted from a User satellite is scattered by the earth before reaching a tracking and delay relay satellite (TRDS) in stationary orbit are considered. An upper bound for the probability of the scattered power density is derived, and numerical results are presented for wide ranges of parameters. In particular, the probability is calculated and displayed for vertical and horizontal polarizations, frequencies of 136 MHz and 2. 3 GHz, wind speeds from 1 m/sec to 12 m/sec, and User satellite heights from 6.578 km to 10.378 km.
