Coherence bandwidth in turbulence
Abstract
Two statistics - coherency and spectrum of amplitude difference - are used to estimate bandwidth limitations for radio wave propagation in a turbulent atmosphere. The statistics are used to estimate the available bandwidth for radio frequencies in close proximity with the 60 GHz molecular oxygen resonant line. Predicted results of .01 percent for the rms differential amplitude variations are obtained for a fluctuation frequency passband from one one-hundred-thousandth Hz to one tenth Hz for a radio frequency passband of 5 GHz centered at 60 GHz.
