Abstract: This paper presents a multi-ultrasonic signal fusion system, which is mainly used in
the robot ultrasonic ranging application. In this system, small ultrasonic echoed signals are
processed by AT89C52 which communicate with the main computer through RS-232 serial port. The system can extract ultrasonic echoed signals precisely, and accomplish multi-sensor data fusion. It lays the foundation for mobile robot to realize fast navigation.
