This paper proposes an ultrasonic location system based on the spread spectrum principle. Compared with the
existing ultrasonic location systems, the proposed system combines the spread spectrum and amplitude modulation
principles. As a result, the proposed ultrasonic location system is advantageous in that it can improve positioning accuracy and detection sensitivity by the spread spectrum principle, it simplifies transmitter and receiver circuits by the amplitude modulation, and it is easy to upgrade its performance by the software functionalities. The advantages and performance of the proposed location system are demonstrated by experiments.
