摘要: An in-line inspection tool is disclosed for inspecting the wall of a pipeline while traveling therethrough. The may include transmitter, signal generator, one or more receivers, and decoder. generator generate pseudorandom signal, an drive transmitter with convolution signal. transmit convoluted to pipeline. One receivers receive from received comprising at least reflection decoder identify within by cross correlating
