Analytical propagation formula for the propagation factor of a phase locked radial laser array beam is derived based on the extended Huygens-Fresnel integral and the Wigner distribution function. Evolution properties of the propagation factor in turbulent atmosphere are studied numerically. It is found that unlike its propagation invariant properties in free space, the propagation factor of a radial laser array beam increases on propagation in turbulent atmosphere, and is closely related to the parameters of initial beam and the atmosphere.
