Abstract

Towards solving the problem that ultrasonic ranging studied in the past was difficult to reach sub-millimeter accuracy in long-distance ranging. In this paper, after analyzing principles of ranging, a system based on the cross-correlation algorithm and an ultrasonic synchronous transceiver platform had a 192 kHz high sampling rate was designed. First, an ultrasonic transceiver platform was designed as a USB audio system with a sound card as the core. Second, a reverse design idea was introduced into the FPGA software to design the accurate clock system, to achieve 192 kHz high sampling rate and transceiver synchronization. Third, to improve the accuracy and stability of ranging, a valid method was proposed to eliminate the jitter of real-time cross-correlation peaks based on this platform. Finally, we conduct extensive experiments, the results show that the range median error is only 0.95 mm in the range of 4.2 m.
