This paper will describe novel techniques and results of the current project to employ advanced signal processing techniques to detect and classify subsurface layers. In particular, a computational fast layer tracking processing technique will be described along with results of the algorithm. It is expected that the ground penetrating radar and the results of current research will assist the Florida Department of Transportation in determining more accurate road layer thickness profiles, assessing road subsurface conditions with less coring, and rehabilitating roads with less manpower than is now required. Such capabilities will allow potentially serious problems to be corrected before they become costly and will also provide a useful tool for future road design and improvement. |
