Abstract

Modern methods for altitude profiling of atmospheric turbulence are discussed. A method for estimating the altitudes of atmospheric layers characterized by strong turbulence, which is an alternative to the Slodar method, is suggested. The method is based on estimation of the spatiotemporal cross-covariances between local wavefront slopes on subapertures spaced in the telescope field of view and a known angular shift of an object observed due to the Sun motion. Turbulence characteristics are estimated for the Big Solar Vacuum Telescope site.

强湍流大气层高度的估算方法

摘要

讨论了大气湍流高度分布的现代方法。提出了一种以强湍流为特征的估算大气层高度的方法，它是斯洛达尔方法的一种替代方法。该方法基于对在望远镜视场中间隔开的子孔径上的局部波阵面坡度之间的时空互协方差以及由于太阳运动而观察到的已知物体角度偏移的估计。估计了大太阳真空望远镜站点的湍流特性。
