Aircraft icing caused by colder water droplets in the clouds has troubled the aviation industry for decades, and it is an essential guarantee for aircraft safe flight to effectively detect aircraft icing. In this paper, the ultrasonic guided wave technique and the structural health technology are used to reconstruct the icing in the monitored area under three kinds of sensors. The experimental results show that the reconstructed image quality is good under the circular layout. In the parallel layout, it can also reflect the icing situation near the center of the parallel line. Under the wing configuration, the presence of ice can be detected, and can roughly reflect the most severe icing area. The idea of S0 modal truncation is also used to reduce the influence of water or other liquids on the reconstructed image quality in this paper.
