Propagation phenomena affecting wireless systems
Robert K. Crane · 2003
This handbook focuses on transmission in and through the lower atmosphere, the region of the atmosphere where weather phenomena occur. The properties of the lower atmosphere are highly variable and change hourly, daily, monthly, and yearly. Their effects on radio wave propagation produce random variations in the amplitude, phase, frequency, polarization, coherence bandwidth, delay spread, and propagation direction of the electromagnetic waves. Knowledge of the statistics of one or more of these effects may be necessary for system design.
