TL;DR: In this article, an analog/digital converter was used to convert a sound reception signal reflected by a target object and received by an acoustic unit of sound reception device, into a digital echo signal.
Abstract: The apparatus (10) has an analog/digital converter (14) converting a sound reception signal reflected by a target object and received by an acoustic unit of a sound reception device, into a digital echo signal A calculation device (17) calculates sound propagation time and time difference of the reception signal based on a pulsed signal produced by an inverse analysis device (16)
