测风经纬仪
aerological theodolite
cefeng)ingweiyi测风经纬仪(aerological‘heodolite)跟踪、测定施放在空中的气象气球的仰角和方位角，用以计算高空风的一种光学仪器。由光学望远镜、转动机构、读数设备、水准器、照明设备，以及三角架、指北针、滤光镜片等附件组成。望远镜可绕垂直轴和水平轴旋转，其物镜与目镜成90度屈折，以便于瞄准位于任何仰角上的空中气球。测风经纬仪还配有倍数较小、视场较大的辅助望远镜，以便于追踪近距离迅速移动的气球。根据气球在各时刻的仰角、方位角及由升速或斜距确定的高度，用测风计算盘点绘气球在水平面上投影点的移动轨迹，可得出各高度的风向凤速。早期的测风经纬仪，是在镜筒外的刻度盘上读取仰角和方位角。经过改进的测风经纬仪，可以从目镜内直接读出角坐标数据，提高了观侧准确度和效率。还有过可打印出角度数据的测风经纬仪。中国人民解放军装备的63式和70式测风经纬仪，测角准确度为0.1。，视场角为2o，放大倍率为20一25倍。80年代应用电信号角度传感器及自动采样计算技术，研制出自动计算测风经纬仪，在跟踪观测气球的同时，计算输出各高度的风向风速等数据。(吴镇中)
