A position vector extraction method using multiple sound wave signal sources is disclosed. The method includes a step where three or more sound wave signal sources generate sound waves; a step where a synchronization signal generator generates synchronization signals; a step where a sound wave transmitting unit transmits the generated sound waves and the generated synchronization signals; a step where a sound wave receiving unit receives the sound waves and the synchronization signals and measures the receiving angles of different sound waves; and a step where a calculation unit measures the distance of each sound wave transmitting unit using the received sound waves and calculates a position vector. According to the position vector extraction method using multiple sound wave signal sources, by organizing a system to extract a position vector of a sound wave signal source using three or more sound wave receiving units, if the angle between the sound wave signal source and two sound wave receiving units converges to 0 or 180, errors in positioning and deterioration of resolution can be prevented using other sound wave receiving sensors.
