The elasticproperties of solids are different since they have form elasticity whichliquids and gases don’t have. Because of this reason, not only longitudinalwaves but also other waves can propagate in solids. Waves propagating in solidscan be used to get information about target location. In this paper, modellingof ultrasonic wave propagation in thin plates is investigated by using a singletransducer and target distance is estimated with adaptive algorithm. Accordingto the obtained results, it can be seen that target location can be estimatedby detecting the starting point of the impulse response with adaptive algorithmsince the delay along with the velocity of ultrasound wave in the modelled wavepropagation is related to the distance between the excitation point and sensor CR - Angelsen, B.A.J., Torp, H., Holm, S., Kristoffersen, K., Whittingham, T.A., 1995.
