Abstract: Airborne ultrasonic waves of frequencies ranging from 44.2 KHzto 47.2 KHz were used to investigated the effect of reflector's symmetry and boundary on the reflected fundamental and second harmonic pulse amplitudes. Symmetry was verified by monitoring reflected pulse amplitudes at various rotational angle settings between the reflector and the transeiver set whereas lateral displacements of the reflector with respect to the transeiver were performed during boundary verification experiments. Time scannings of a reflector were also dine and its orientations were deduced.
