摘　　要：In this paper,the eavesdropping model based on eavesdroppers near legitimate users,and the effect of atmospheric channel correlation on the physical layer security(PLS)of the free-space optical(FSO)link are analyzed.According to the joint probability density function(PDF)and cumulative distribution function(CDF)of Gamma-Gamma(G-G)distribution,a new closed-form expression of interception probability is derived.Numerical results show that the interception probability of the FSO system depends on turbulence intensity,channel correlation and radial displacement attenuation of eavesdroppers.
