Guided Wave based Structural Health Monitoring greatly benefits from directional scanning. In contrast with conventional phased array approaches, the novel frequencybased beam steering concept and the associated signal processing presented in this work enable imaging of two-dimensional (2D) areas through the output of a single, dual channel sensor.
