Monostatic heterodyne lidar performance: the effect of turbulent atmosphere
Abstract
The reduction in the SNR of a monostatic heterodyne lidar due to the presence of atmospheric refractive turbulence in the medium intervening between the lidar and the target was calculated. The previous approximations of independent refractive turbulence on outward bound and return paths and a quadratic form for the wave structure function were erroneous. An exact calculation shows that previous results overestimated signal degradation.
