On the Use of Microwave Holography to Detect Surface Defects of Rails and Measure the Rail Profile [PDF]
Sensors, 2019 The use of microwave holography for detecting rail surface defects is considered in this paper. A brief review of available sources on radar methods for detecting defects on metal surfaces and rails is given. An experimental setup consisting of a two-coordinate electromechanical scanner and a radar with stepped frequency signal in the range from 22.2 ...
