Low cost binaural system based on the echolocation
Ultrasonic sensors offers attractive features at an affordable
cost. The main problem faced by the use of these devices is that the
data obtained are not so easy to interpret , restricting their efficiency.
This paper describes a binaural sensor system that is able to determine
the coordinates of an object or a target in a two-dimensional space,
focusing on mathematical and signal processing techniques to provide
accurate measurements and increase the system reliability. The proposed
work consists only of low cost components, which aims to demonstrate
that improvement is possible. Experimental tests, performed in different
scenarios, reported good accuracy and repeatability of the measurements.This work is financed by the ERDF-European Regional
