Fast simulation of spot location for space laser communication link in the process of tracking the time-varying turbulence phase screen, which is characterized by inverse Fourier transform, and generate the simulated Karl Mo Golov method combined with low frequency sub harmonic information (Kolmogorov) random turbulence phase screen, through the relative movement between the receiving aperture and random phase screen, different parts of the moment and the phase screen to simulate turbulent flow through the aperture movement, thus avoiding the need for spot location each time the process to re generate the random phase screen, makes the simulation process saves a lot of time. The method is simple, fast and effective.
