| Abstract: |
| With the wide application of ultrasonic ranging, requirement for the r
anging precision is higher and higher. How to improve the precision of ultrasoni
c ranging has become the research focus. This paper summarizes the methods of im
proving ultrasonic ranging precision that have been applied or recognized,and cl
assifies the methods according to the factors influencing the ultras
onic ranging precision. |
