The effects of turbulence induced pathlength fluctuations on the accuracy of single color and two color laser ranging systems are examined. Correlation and structure functions for the path deviations are derived using several proposed models for the variation of C(n)(2) with altitude. For single color systems, random pathlength fluctuations can limit the accuracy of a range measurement to a few centimeters when the turbulence is strong (C(n)(2) ~ 10(-13) m(-2/3)), and the effective propagation path is long (>10 km). Two color systems can partially correct for the random path fluctuations so that in most cases their accuracy is limited to a few millimeters. However, at low elevation angles for satellite ranging (<20 degrees ) and over long horizontal paths, two color systems can also have errors approaching a few centimeters.
研究了湍流引起的路径长度波动对单色和双色激光测距系统精度的影响。利用几种提出的关于C(n)(2)随高度变化的模型，推导了路径偏差的相关函数和结构函数。对于单色系统，当湍流较强（C(n)(2) ~ 10(-13) m(-2/3)）且有效传播路径较长（>10 km）时，随机路径长度波动会将距离测量的精度限制在几厘米以内。双色系统可以部分校正随机路径波动，因此在大多数情况下其精度限制在几毫米以内。然而，在卫星测距的低仰角（<20度）和长水平路径上，双色系统的误差也可能接近几厘米。
