Laser atmospheric flicker index prediction method and system

The invention discloses a laser atmospheric flicker index prediction method and system. The method comprises the following steps: constructing an atmospheric turbulence simulation model; recording a light intensity pattern after the reference light beam passes through the atmospheric turbulence simulation model, and calculating a flicker index after the reference light beam passes through the atmospheric turbulence simulation model; taking the light intensity pattern and the flicker index as training data, and sending the training data into a neural network for training to obtain a trained neural network model; and sending the light intensity pattern of the unknown light beam into the neural network model, and predicting the flicker index of the unknown light beam. The method overcomes the defects that in the prior art, calculation is complex, consumed time is long, influences of external noise factors are difficult to eliminate, and robustness is poor, and respective prediction of the atmospheric flicker ind
