Abstract
A Trihedral rectangular ultrasonic reflector is made of Perspex, whose characteristic is that the reflecting ultrasonic beam follows an opposite direction from that of the incident beam. When the reflector is used as the "target" for measurements, the distance derived is the distance between the transmitter and its top, regardless of its orientation, under certain limitations.
Keywords: ultrasonic, Trihedral rectangular, distance measurements.
