摘　　要：介绍了一种大型电波暗室天线支架精密定位的方法。该方法利用光学准直测量的原理，在高精度电子经纬仪的基础上，引入准直测量功能和激光指示功能，在45m的距离上，将准直调整范围扩展到±0．1°，实现了标准天线支架的精密定位。An alignment method for standard antenna support of large anechoic chamber is presented . It is based on the principle of auto - collimation. A high precision digital theodolite is employed, which is provided with auto- collimation function and laser indicator. With this method, the range for auto- collimation can be rendered to ± 0.1° in the 45m distance. That meets the need for precision adjustment of antenna position.
