This paper introduces ultrasonic 3D position measurement system that will estimate the location of a wave source by triangulating its position based on a multiple-frequency continuous wave (MFcw) to three receivers fixed to an inertial frame of reference. The Typical application of this system is finding the location of the transmitter that may be fixed on(More)
