Abstract:

Spectral inversion method is used to simulate the distortions of phase screen. By setting the parameters of laser emission system, the peak Strehl ratio of far field spot of emitting light and spot of receiving light is calculated. According to the definition of the correlation of Pearson, the characteristic parameters of the change trend of calculated peak Strehl ratio, correlation coefficient with the transmission effect (turbulence effects characteristic parameter D/r0, thermal blooming heat distortion parameters of Nd) are obtained. The relative deviation of light emission and receiving light Strehl is analyzed, and its rationality is validated. To study the light emitted By analyzing the relative error and correlation coefficient, the Strehl ratio differences between the emitting light and receiving far-field spot is researched.

Key words: atmospheric transmission, phase screen, correlation coefficient
