The use of non-metallic composites that are durable, low cost, and lightweight is growing fast in various industries like the oil and gas industry. A commonly used form of these materials is in the shape of pipes. Such pipes can be damaged due to material loss (defects and holes), erosions, and more which may cause major production failures or environmental mishaps. To prevent these issues, non-destructive testing (NDT) methods need to be employed for regular inspections of such components. Since traditional NDT methods are mainly used for metallic pipes, microwave imaging has recently been proposed as a promising approach for examination of nonmetallic pipes. While microwave imaging can be employed for inspection of multiple layers of pipes, the effect of eccentricity of the pipes (undesired distance between the centers of multiple pipes which are supposed to be concentric) can impose additional imaging errors. For the first time, we study the effect of eccentricity of the pipes on the images reconstructed using near-field holographic microwave imaging when imaging double pipes through simulations. To have a realistic study, we add artificial noise to the simulated data.
