A mobile android tool for simplified GPR data processing in construction applications

This work presents a new GPR signal processing tool for mobile devices, which uses the free Android platform in smartphones and tablets. The developed application is able to display and process radargrams without using the most common commercial software applied for GPR signal processing. These existing applications have usually been developed for advanced signal processing, which results in complex processes and requires large computational resources. Therefore, the aim of this work was to develop a simplified and intuitive tool, which allows speeding up the GPR signal processing. For such purpose, the application implements basic filters to optimize the GPR images analysis and to facilitate data interpretation. Different tools have also been implemented to obtain interesting geometric measurements, such as thicknesses and diameters in rebar or piping. Thus, any non-expert user on the GPR technique could generate preliminary in-situ results using conventional smartphone or tablet devices.
