摘要：

Permanently installed guided wave sensors are an attractive option for pipeline inspection as they offer significant inspection cost reductions and enhanced damage monitoring capabilities. This paper discusses the advantages of baseline subtraction in the pipeline inspection context as well as methods to address the unique challenges when compensating for signal changes due to environmental effects other than the growth of damage. It is shown that through the use of baseline subtraction and compensation for environmental effects it is possible to achieve significant damage sensitivity improvements over conventional ultrasonic guided wave inspection.
