Abstract:
1. A system, comprising: a mobile ground penetrating radar (GPR) system, comprising: wherein a variable time delay results between a time when the GPR scan data is collected and a time when the position data associated with the GPR scan data is recorded; an encoder capture module (ECM) adapted for attachment to the apparatus, the ECM comprising: a data acquisition system coupled to the output of the ECM and configured to receive GPR scan data from the GPR sensor, positioning data from the positioning sensor, and the ECM signals from the ECM, the data acquisition system configured to generate a DAS timestamp in response to each ECM signal and to associate the DAS timestamp with the GPR scan and the GPS position associated with the GRP scan, so as to substantially eliminate the variable time delay.
