抄録

In many engineering fields, distance to target is fundamental and very important information. Acoustical signal, such as audible sound or ultrasonic, often plays an essential role in measurement of distance. To measure distance, the time delay of reflected wave measured with reference to transmitted pulse wave, i.e. time-of-flight (TOF) is used typically. This method, however, can not measure short distance because the transmitted wave, which has not attenuated enough as of reception of reflected waves, suppresses the reflected waves for short distance. Meanwhile, in the research field of microwave radar, to measure distances to multiple targets even if short, a novel method by using standing wave has been recently proposed. We apply the fundamental principle of this method to estimation of short distance for multiple targets using audible sound. In this paper, we focus our attention on audible band-limited noise. To verify the validity and effectiveness of our method, we perform computer simulations and experiments. As a result, it has been confirmed that short distances to multiple targets, such as the distances to two targets located at 0.1m and 1m, can be estimated properly by our method.
