Model Simulation of Ground Penetrating Radar using GPRMax to Detect Porang Tuber

This study aims to design and simulate the GPR (Ground Penetrating Radar) with GPRMax software to detect the location and estimate the depth of the Porang tubers underground. The processing signal used in the GPRMax was A-Scan. The simulations were performed by varying the distance between soil surface and Porang tuber. The results of GPRMax simulation using A-scan was able to detect the location of the tuber underground. The results of the detection of Porang tuber depth showed A-scans was effective at a distance of 9 and 10 cm with error rate of less than 10%.
