Embodiment Construction
[0020] see figure 1 , figure 1 It is a flowchart of the present invention. The steps of radar data processing for railway subgrade detection without sleeper interference are as follows:
[0021] Firstly, the vehicle-mounted subgrade radar continuously samples on the detection vehicle running at approximately constant speed to obtain the raw data of the subgrade detection, which not only includes useful signals that can reflect the condition of the railway subgrade and various noises caused by other electromagnetic interference sources, but also includes Sleeper interference signal. The screened antenna used in the ground-penetrating radar antenna of the railway subgrade, the receiving antenna first receives the direct wave, and the medium between the transmitting and receiving surface of the antenna and the upper interface of the sleeper is only air with uniform electromagnetic characteristics, no reflecting interface, and no reflected signal. When the antenna position is n...
