In this paper a new method for measurement of proposed is mobile object coordinates. For measurement of spatial coordinates of the object combination of different methods was use. With the on object mounted low-frequency ultrasonic transducer emitted signals are picked up by two ultrasonic receivers. Position of the object is determined by the binaural method. For improvement of accuracy and noise robustness the delay time of the ultrasonic signals is determined on-line using correlation processing. Algorithm for tracking of ultrasonic pulses in the time domain was developed. Analysis of the measurement uncertainties and the results of experimental investigation are presented.Downloads
