Increasing signal to noise ratio of acoustic echoes by a group of spaced apart acoustic transceiver arrays
First Claim
1. A method for evaluating a content of a bin, the method comprising:
- transmitting by multiple acoustic transceiver arrays that are spaced apart from each other and have partially overlapping fields of views that form an overlap area on a surface of the content, a plurality of acoustics pulses in an at least a partially overlapping manner towards the overlap area to generate, at the overlap area, an acoustic interference pattern that comprises multiple fringes;
wherein each acoustic array of the multiple acoustic transceiver arrays comprises transducers;
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;
wherein a distance between a pair of acoustic transceiver arrays is at least ten times a distance between centers of the transducers of each acoustic transceiver array of the pair of acoustic transceiver arrays.

Abstract
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.
