description | By analyzing the effect of the degree of polarization (DoP) of the partially coherent Gaussian Schell-model (GSM) beam on a heterodyne system of an uplink path and a downlink path, we developed an innovative and noteworthy theory according to which σ<i><sub>sy</sub></i> (signal beam waist radius in the <i>y</i> direction component) and <i>δ<sub>Syy</sub></i> (coherence length of the signal beam in the <i>yy</i> direction component) had a more significant impact on heterodyne efficiency and DoP than the turbulence term on uplink and downlink paths. Namely, the DoP and heterodyne efficiency of an uplink path are higher than that of a downlink path when σ<i><sub>sy</sub></i> > 0.02 m or <i>δ<sub>Syy</sub></i> ≥ 0.03 m. This innovative rule provides an efficient way for increasing the heterodyne efficiency of a signal beam propagating along an uplink or a downlink path channel in satellite-ground communication links in free-space optical heterodyne detection communication. |
