Results from the 19- and 28-GHz COMSTAR satellite propagation experiments at Crawford Hill
Abstract
Some of the most fundamental limitations on the performance of satellite communication systems at frequencies greater than 10 GHz result from strong interactions of radio waves with rain and ice in the lower atmosphere. The economic design of reliable satellite communication systems operating at such frequencies depends, therefore, on detailed knowledge of the effects of these interactions. The 19- and 28-GHz beacons on the Comstar satellites have been used to make unique space-earth propagation measurements at Crawford Hill, NJ. The major emphasis was on depolarization measurements important to dual-polarized satellite communication systems and on phase and amplitude dispersion measurements important to wideband digital systems. A review of the obtained results is provided for the convenience of the engineering community.
