Railway track inspection using gpr
WebAccording to literature, first attempts of using GPR as a potential method for assessing the conditions of ballasted railway track-beds date back to the first noughties [10, 11]. In these experimental activities, surveys were conducted using GPR systems with central frequencies below 500 MHz. More recently,
