Systems and methods for detecting anomalies, such as corrosion, on intern al surfaces of hollow elongate bodies, such as pipelines. The pipeline is tr eated as a circular waveguide, and a fast rise time pulse or a spectrum of e lectromagnetic waves is launched down the waveguide to perform time domain, or equivalent of time domain (e.g., frequency domain), reflectometry. Anomal ies in the internal structure of the pipeline cause reflections which can be measured and related to the physical parameters of the pipeline structure a nd identified to a particular location. |
