Distance measuring equipment has a rough distance measuring circuit (18) using a time delay circuit and a precise distance measuring circuit (31) for measuring the orientation of the vector of a carrier wave to determine the distance, the sum of which is the final output. The rough distance measuring equipment (18) has a long measurement span but low precision. The precise distance measuring equipment (31) has a short measurement span but high precision. The combination provides distance measuring equipment having a long measurement span and high resolution and capable of implementing precise measurement. |
