    摘要: An anomaly on an elongate conductive member is detected by causing a source electromagnetic wave to propagate in a first direction along the elongate conductive member such that the source electromagnetic wave passes through the at least one anomaly. The anomaly causes a reflected electromagnetic wave to propagate in a second direction along the elongate conductive member. The second direction is opposite the first direction. The electric field of the reflected electromagnetic wave is sensed. The magnetic field of the reflected electromagnetic wave is sensed. A direction of propagation of the reflected electromagnetic wave is determined based on the electric field of the reflected electromagnetic wave and the magnetic field of the reflected electromagnetic wave.

    摘要: Systems and methods for detecting an anomaly on an internal surface of a hollow, elongate, metallic pipe structure. An anomaly detection system employs an access port, an antenna, a signal source, and a signal analyzer. The access port allows physical access to an interior of the pipe structure. The antenna extends into the interior of the pipe structure through the access port. The signal source is operatively connected to the antenna and is capable of causing the antenna to cause a test signal to be conducted along the pipe structure such that the anomaly reflects at least a portion of the test signal back towards the antenna as a reflected signal. The signal analyzer is operatively connected to the antenna to analyze, in a frequency domain, the reflected signal.

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