Accurate Shallow-Buried Object Detection Using Bistatic Drone-Mounted Ground Penetrating Radar

This paper shows a study of possible scenarios of using bistatic drone-mounted ground penetrating radar configuration for an accurate shallow-buried object detection. Objects of interest are anti-personnel landmines, which are often made of plastic, with a small amount of metal parts. Because of payload limitations, the system must be small, lightweight and highly efficient. The system is intended in a microwave range of 0.6 GHz - 2.6 GHz. Signal reflections are recorded in frequency domain which correlates to Stepped Frequency Continuous Wave measurements and processed through Inverse Fast Fourier Transformation for time domain analysis. Recording in multiple spatial positions enables B-scans generation for object detection. Polarimetric approach and its effects on target detection accuracy will be investigated in the paper.
