INCREASING SIGNAL TO NOISE RATIO OF ACOUSTIC ECHOES BY A GROUP OF SPACED APART ACOUSTIC TRANSCIVER ARRAYS

摘要

A method and a system for evaluating a content of a bin, the method may include: transmitting by multiple acoustic transceiver arrays, a plurality of acoustics pulses in an at least partially overlapping manner towards an expected location of the content to generate an acoustic interference pattern that comprises multiple fringes; detecting by an acoustic transceiver array a first fringe of the acoustic interference pattern and providing a fringe detection signal; and processing the first fringe detection signal to assist in a provision of a first estimate related to the content. A distance between a pair of acoustic transceiver arrays is at least ten times a distance between transducers of a same acoustic transceiver array.
