Abstract:
Regarding the mileage deviation caused by speed difference of the antenna or untimely mileage marking by the detector during tunnel lining detecting by ground penetrating radar, a mathematic model to illustrate the relationship between the detected mileage and actual mileage is established. This model can be used for mileage correction and to improve the accuracy of detection.
