利用谱反演法来模拟畸变相位屏,通过设定激光发射系统的特征参量,计算得出发射光的远场光斑与接收光的远场光斑的峰值Strehl比,并根据Pearson相 关性的定义,计算得出峰值Strehl比、相关系数大小随传输效应的特征参量(湍流效应特征参量D/r0、热晕热畸变参量Nd)变化趋势。分析发射光与接 收光的Strehl比的相对偏差,验证相关系数的合理性。通过分析其相对偏差和相关系数来研究发射光与接收光远场光斑Strehl比的差异性。

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 Nd) are obtained. The relative deviation of Strehl of emitting light and receiving light is analyzed, and its rationality is validated. By analyzing the relative error and correlation coefficient, the Strehl ratio differences between the emitting light and receiving light far-field spot are researched.
