Abstract
The authors describe a multi-antenna microwave receiver system
that monitors an unmodulated beacon transmission from a geosynchronous
satellite. The system interferometrically measures temporal fluctuations
in tropospheric differential path length, which include fluctuations in
precipitable water vapor, over 100to 400-meter baseline lengths. Over
300 s, the system root mean square error (rms) noise is 0.01 radian.
These observations will facilitate studies of air parcel motion as the
means by which the causative, phase-corrupting atmospheric
inhomogeneities drift over the array. The resulting data will be useful
for studies of convective boundary layer turbulence, a region difficult
to fully access
