Backscatter amplification effect for a reflected partially coherent Gaussian beam in turbulent medium

The enhancement effect of backscattering for laser propagation through turbulent atmosphere

“…represents the backscattering conventional term on the non optical axis. Comparing the two terms, we can get the backscattering enhancement coefficient [16] …”

“…Fig. 1 Beam two way path transmission diagramAccording to the generalized Huygens-Fresnel principle and the theory of mutual interference effect, the expression of optical intensity at the receiver is[16] …”
