<p>PURPOSE: A location positioning system and a method using phase-difference detection are provided to obtain a fast response by reducing the amount of calculation since there is no need to restore an original signal. CONSTITUTION: A location positioning system and a method using phase-difference detection is comprised of steps: collecting the signals of a signal source through two sensors(10) having different locations; ADC converting the signal; a dividing the signal of each channel into at least one frequency; and calculating the phase of a frequency of the each channel.</p> |
