TROPOSPHERIC PHASE FLUCTUATIONS AT S-BAND,

Abstract

A tropospheric propagation experiment to obtain the mean square phase fluctuations at 2250 mc over a 48-mile path is described. Experimental data pertain to a 10-minute time interval on a meteorogically quiet day. Results indicate that the mean square value of the phase fluctuations was about 6.2/1000 square radians for this particular day. Estimates of the scale size and the intensity of the fluctuations of the refractive index are given. The experimental equipment used in this experiment consisted of four phase-locked interferometers having baselines of 100 m and 100 m north-south and east-west. The 2250-mc signal source was carried on board a B-57 aircraft at a mean altitude of 40,000 ft. (Author)
