摘要：

The cross-spectral density (CSD) matrix of radially polarized Lorentz correlated beam (RPLCB) is proposed, and the degree of coherence of RPLCB is described by Lorentz function. The matrix elements of RPLCB in anisotropic turbulent ocean are obtained. The intensity and polarization of RPLCB are studied via numerical simulations. The evolution of intensity of RPLCB in free space will evolve from ring shape into Lorentz shape caused by Lorentz function, and the Lorentz shape of RPLCB in turbulent ocean will be destroyed by turbulence and become a Gaussian profile at the longer distance. The RPLCB with a smaller coherence length will turn into Lorentz shape faster on propagation. The degree of polarization of RPLCB will decrease as distance increases, and the depolarization of RPLCB in turbulent ocean is more obvious than the same RPLCB in free space.
