9 June 2014 Atmospheric turbulence effects on a monostatic and bistatic retroreflecting link
Author Affiliations +
Experiments were conducted over a retro-reflecting link using both a monostatic and a bistatic laser interrogator that operated over adjacent terrestrial paths of ranges between 2 and 4km. Data communications parameters were monitored on the bistatic channel and irradiance measurements were recorded on both interrogators simultaneously. The off-axis bistatic receiver was 75mm in diameter and showed the advantage of both aperture averaging and uncorrelated irradiance components in comparison with the 28mm receiver used in the on-axis monostatic system. The normalized flux variance measured in the bistatic receiver peaked at a value close to 1 while the on-axis system saw corresponding levels of about 10 under sunlit midday conditions.
