Abstract :
Range finder is an important sensing device for underwater robots to measure the height of the robot from the bottom to avoid the damage. This paper firstly took a simulation processing on the echo signal by MATLAB, verified the feasibility of the program, secondly made a detailed description about the implementation process of the cross-correlation algorithm in FPGA, and improved the reliability of the measurement by determining adaptive noise threshold.
