Abstract
A transient-based time reversal (TR) technique for acoustic imaging of a pressurized water supply pipeline is provided. Measured multi-input-multi-output (MIMO) imaging data at high frequency (10kH-100 kHz) are processed by an adapted Time Reversal-MUltiple SIgnal Classification (TR-MUSIC) algorithm to provide a high-resolution image of a pipeline section about 100 m long. The resultant image reveals the pipe wall inner and outer condition, and incipient and existing defects at a scale up to millimeters. The technique is tested and validated in a laboratory environment and in a large-scale facility on pressurized water-filled viscoelastic high-density polyethylene pipes. Furthermore, the technique can be applied to different fluids and pipe materials. In addition, the technique is computationally efficient, and nondestructive. The technique requires only local intrusion for placing transducers at an access point.
