Based on the generalized Huygens-Fresnel principle, the modified von Karman spectral model, and the atmospheric structure constant model promulgated by International Telecommunications Union-Radio (ITU-R), the average intensity analytic equation of partially coherent Gaussian-Schell model (GSM) beams for upstream transmission can be derived. The expression for the average intensity of a GSM beam transmitted downward to a receiver after returning from an angular reflector is obtained, and the change in the average intensity of the GSM beam during the upward-downward transmission is analyzed.

摘要

Based on the generalized Huygens-Fresnel principle, the modified von Karman spectral model, and the atmospheric structure constant model promulgated by International Telecommunications Union-Radio (ITU-R), the average intensity analytic equation of partially coherent Gaussian-Schell model (GSM) beams for upstream transmission can be derived. The expression for the average intensity of a GSM beam transmitted downward to a receiver after returning from an angular reflector is obtained, and the change in the average intensity of the GSM beam during the upward-downward transmission is analyzed.
