Real-Time Processing of Continuous Doppler Signals for High-Speed Monitoring of Rail Tracks

In the rail industry, existing railroad tracks are carrying heavier and heavier train loads, instead of constructing new rails and distributing trainload tonnage [1,2]. As the average load per track increases, there is a growing concern about the critical flaws in the rail. Consequently, it is necessary to assess the rail integrity by means of rapid nondestructive detection of rail defects.
