Crosstalk is a common problem occurring with arrays of multiple ultrasonic sensors (sonars) in obstacle detection and avoidance systems. This paper presents a novel method that might allow the use of data generated by crosstalk to generate more reliable and accurate object detection. This is accomplished by assigning a unique code to the signals emitted by each sonar, so that the source sonar can be identified even if its signal’s echo is received by another sonar. Using geometric interpolation… CONTINUE READING
