Monitoring Infiltration Process Seamlessly Using Array Ground Penetrating Radar
Agricultural & Environmental Letters, 2016 Because an array ground penetrating radar (GPR) electrically switches any antenna combinations sequentially in milliseconds, both common-offset gather (COG) and multi-offset gather (MOG) data can be acquired almost seamlessly.
