Research and application status on domestic ultrasonic ranging

摘要

Based on the principle of ultrasonic ranging,this paper described the domestic research status of ultrasonic echo signal processing,new transducers designing.It also introduced the application of ultrasonic ranging technology in the field of domestic liquid-level measure,mobile robot obstacle avoidance,vehicle collision avoidance and profile measurement of surface.After that,this paper analyzed the problems in ranging system and the solutions.The developmental direction and research progress in ultrasonic ranging were also presented.
