摘要： A device and method for nondestructively inspecting, measuring, and/or detecting metallic. The device may enable multiple synthetic apertures for measurements simultaneously. The device includes a transmitter coil array and a receiver coil array wound around a core. The receiver coil array includes multiple receiver coil sections built with gaps in between adjacent sections to form multiple associated apertures. An analog electrical network is coupled to the multiple receiver coil sections to enable multiple combined synthetic apertures to be operated together for the transducer to conduct measurements simultaneously to provide multiple outputs associated to the multiple synthetic apertures. Measurement signals can be combined to build a processed signal that can represent more accurate information from the target.

摘要： Casing signals generated by an EMAT in a borehole are processed using at least two orthogonal band-limited filters. The band-limited filters may include Gaussian or Cauchy Wavelet filters. By using the Hilbert transform, an envelope of the filtered signals is determined and amplitudes and arrival times of individual arrivals are estimated. These can be used to estimate casing and cement properties.
