Ultrasonic sensor is widely used in robot, automobile, automatic production line and so on, but its detection angle is limited, therefore, multiple ultrasonic sensors are often needed to expand the detection range of distributed structures such as parallel or surround. Multiple ultrasonic probes work at the same time, and very close each other, it will cause crosstalk problems. The chaotic sequence is introduced into the detection signal in the system of ultrasonic receiving and transmitting, it can improve the reliability of detection information and efficiency, realize multi probe synchronously work without crosstalk. Simulation and experimental data show that the system can effectively detect in the range from 0.08 to 4.87 meters, the average error is less than 1.16%, which proves that this method is feasible.
