SAR-Light: Uav-Embedded SAR Platform and Its UHF Band Development for Mines Detection

SAR-Light is a drone-embedded SAR imaging tool developed by ONERA, the french aerospace lab since few years with full polarimetric X- and C-bands imaging capabilities. This study focus on the recent development of the UHF band for SAR-Light. As UHF band allows radar signal penetration through the environment, it is generally a privileged band to detection of hidden objects such as mines. Moreover UAV SAR sensors are flexible that allow fast acquisitions in different trajectories. A measurement campaign dedicated to mines detection is presented to demonstrate the potential use of UHF UAV SAR and additional degrees of freedom for mines detection.
