Abstract :
The goal of this paper is to present a case study that considers the non-destructive testing problem of a cured in place pipe sample. We employ synthetic aperture radar (SAR) to remotely detect artificial boreholes in the dielectric object. Broadband frequency modulated signals are generated and recorded by a vector network analyzer in the frequency range between 75 and 100 GHz. Subsequent processing of the signals in time-domain reveals the locations of the structural defects.
