The comparison and analysis the ground penetrating radar GPR equipments on electromagnetic radiation data / Akid Rais Noorizan

The Ground Penetration Radar (GPR) becomes a popular device in investigation of the
underground utilities in recent years. GPR use of electromagnetic radiation to detect
and record the properties of underground utility. Besides that, GPR can analyse the type
and position of utility objects. However, the performance accuracy of GPR models is
an important issue that should be considered. This research conducts between two
models of MALA ProEx GPR and Noggin Smart Cart 250MHz GPR by focusing on
the basic principle of GPR, accuracy analysis and calibration method implemented on
GPR. The survey work has been performed to identity the capabilities of GPR
equipments with same frequency which is 250MHz to detect underground utility objects
at Gurun, Kedah which required steps of study area preparation, data collection, data
processing and interpret the results of data. In this study area were buried the utility
objects of PVC pipe and Metal pipe and their original depth were 2.25 metres and 2.10
metres respectively. These surveys were organised on a grid pattern across the surface
of land in the test facility. In addition, data analysis was carried out to compare between
two models of GPR equipments. This research provide proper guideline and assists
surveyors to select the suitable equipments regarding on application especially on utility
mapping in terms of accuracy.
