“…Li et al [5] developed a mathematical model for a heterodyne detection system for partially coherent Gaussian Schell beams under the Tatarskii turbulence spectrum in 2015. Furthermore, some of the authors of this paper investigated the effect of signal beam propagation in atmospheric turbulence on heterodyne detection, e.g., angle-of-arrival fluctuation [3], beam mode of the partially coherent Gaussian Schell-model beam [1,2], irradiance and phase fluctuations [13] and wavefront correction [10]. However, these works were based on the vector theory of partially coherent light fields or Gaussian beam.…”

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 σsy (signal beam waist radius in the y direction component) and δSyy (coherence length of the signal beam in the yy 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 σsy > 0.02 m or δSyy ≥ 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.
