摘要
论述了利用三只超声换能器测量距离和角度的原理，给出了硬件电路原理图和软件流程图，分析了引起测量误差的主要原因，提出了减小系统误差和随机误差的措施。
The principle of range and angle finding by three supersonic tracsformers in analysed, Electric circuit schematic chart and software flow chart are given. Main sources of errors in measuring are analysed and some measures are given to weaken systematic error and random error.
