Beschreibung
Zusammenfassung:	An apparatus for inspecting an operational condition of a rail track from a railcar includes an antenna positioned on the railcar that directs radar signals toward the rail track and collects radar signals returned from the rail track. A radar transceiver is connected to the antenna and supplying the radar signals to the antenna. The radar transceiver receives radar returned signals from an interaction of the radar signal with the rail track. A controller is connected to the radar transceiver for controlling transmission of the radar signals from the radar transceiver and receipt of the radar returned signals. A signal processing unit is connected to the controller and a sensor unit that supplies input data to the signal processing unit. The signal processing unit processes at least the input data and the radar returned signal to produce processor output data and to determine the operational condition of the rail track.
