Abstract (in Japanese) (See Japanese page) 
(in English) In many engineering fields, distance to targets is very important information.General distance measurement method uses time delay between transmitted and reflected waves, but it is difficult to estmate short distance.On the other hand, the method using standing wave to measure short distance is known in the field of microwave radar.We have applied this method to audible sound, and the validity of our method has been shown through simulations and experiments.

In this report, we implement our method in microcomputer, and show the small distance measurement system using our method.Finally, we confirm the effectiveness of our proposed system by applying it to the actual sound field.
