| Abstract: | A new ultrasonic raging system applied in the mine detection robot is discussed.Varieties of hardware and software technologies are used to enhance precision of time point detection and reduce the range of blind zone.Experiments prove that the blind zone is small,the performance is stable in far and near measure range,and the accuracy accords with engineering requirements in this system.It can be used in the environment which requires small measuring blind zone and relatively high measuring accuracy. |
