电磁波测距仪跨河水准精度分析

Analysis on the level precision surveyed across river with the electromegnetic range finder

对测距仪跨河水准测量的精度进行了分析，该方法的测量精度可以达到工程三等水准的精度要求，也有可能达到国家三、四等水准测量的要求。

The level pricision surveyed across river with the range finder is analyzed, The survey precision with the method can meet 3 clase of engindeering level pricision, and may possibly reach 3 or 4 class of national level survey precision.
