摘　　要：为满足导航测风技术的发展,提高高空风的探测精度,从高空风的探测原理出发,建立了基于地心大地坐标系的高空风计算方法,并把计算结果与站心坐标系及WGS-84坐标系中的结果进行比较。分析表明:不同坐标系中高空风计算结果具有较好的一致性;对于传统的高空风探测,仍可在站心坐标系中进行高空风的计算;对于导航测风,则应根据位置参数直接在地心大地坐标系中进行高空风的计算。To meet the requirements of navaid wind-finding development,and improve the accuracy of upper wind detection,a new method of upper wind calculation in the geocentric coordinate was proposed based on the basic principle of upper wind sounding.The upper wind derived from this method and from the methods in the coordinate WGS-84 and the station-origin coordinate was calculated.Analysis shows that the results derived from different methods were uniform,and the upper wind can be calculated in the station-origin coordinate with the traditional sounding methods,but it should be directly calculated from the position parameters in the geocentric coordinate for navaid wind-finding.
