Summary
UAV-mounted GPR-SAR systems: a key technology for detecting buried explosive threats – by Dr. Maria Garcia-Fernandez, University of Oviedo (Spain)
In the field of subsurface sensing, Ground Penetrating Radar (GPR) is a key technology for detecting buried explosive threats, such as landmines and Improvised Explosive Devices (IEDs). The talk will be focused on GPR systems mounted on board Unmanned Aerial Vehicles (UAVs), leveraging the Synthetic Aperture Radar (SAR) paradigm to provide high-resolution radar images of the subsurface. This kind of systems brings together the advantages of UAVs (e.g., enabling the inspection of difficult-to-access areas without interacting with the soil) and the capability of radar systems to detect buried targets. In this talk, several prototypes of UAV-mounted GPR-SAR systems tested in realistic scenarios will be presented, showing their success in detecting buried threats in realistic scenarios. The current challenges and future trends of this technology will be also discussed.
Towards portable radar imaging solutions: freehand systems and the computational imaging paradigm – by Dr. Guillermo Alvarez Narciandi, University of Oviedo (Spain)
Electromagnetic imaging enables to penetrate through some optically-opaque materials. This ability to ‘look inside’ objects and structures is incredibly useful — with applications ranging from medical diagnostics and security screening to food inspection, to name a few. However, conventional imaging systems usually involve significant hardware complexity and cost, which prevents their widespread adoption. In this talk we will present the concept of freehand radar imaging and some prototypes developed by our team, which enable to retrieve high-resolution radar images using a compact radar module and pave the way for handheld imaging systems. Furthermore, we will discuss how the computational imaging paradigm, which relies on a spatially diverse illumination with metasurface-based antennas, has emerged as a promising alternative to the traditional synthetic aperture radar paradigm.
