Analysis of interference characteristics of ground penetrating radar railway sleepers
Diseases of railway subgrade may affect the safety of railway transportation.Ground penetrating radar can per-form efficient and continuous imaging of subgrades and has been widely used in non-destructive testing of railway subgrades.When ground penetrating radar is used to detect railway subgrade diseases,sleeper interference affects the identification and lo-cation of subgrade diseases.The characteristics of sleeper interference in the time domain,frequency domain,space domain,time-frequency domain,space-frequency domain,and statistical correlation are analyzed,respectively,which provides a basis for further selection of sleeper interference suppression methods.
