Radio Path Length Stability of Ground-To-Ground Microwave Links

摘要

A series of eight field experiments were conducted in 1958 and 1959 to study the variation in the apparent path length of ground-to-ground microwave links (i.e., the variations in phase of 9400 Mc/s signals) and the corresponding variations in radio refractive index and other atmospheric parameters measured at the path terminals. The report summarizes the results obtained on paths in Colorado and Florida. It also includes an analysis of long-term variations in the apparent path length and associated variables recorded during each experiment, and a power spectrum analysis of short-term variations in apparent path length and refractivity.
