Investigation of the influence of the transducer positioning angle deviation on the 3D reflections from a triangle reflector

Abstract

Objective of this study was to investigate the influence of the transducer positioning angle deviation from its supposed position on the 3D reflections from a triangle reflector. For that an acoustic computer model using the Huygens approach, which enables calculation of the signals reflected by the triangles in 3D space was used. Modelling was performed at different deflection angles of triangles with respect to the transducer and at different transducer deflection angles from its supposed position for each triangle angle. The performed simulations show that even small deflection of the transducer from its supposed position deteriorate the obtained image of the inspected object
