The measurement of TDOA short baseline

Abstract

The main aim of this work was to measure, verify and evaluate accuracy of target-location estimation in time difference of arrival (TDOA) method. Measuring workplace for TDOA measurement was assembled by using three receiving antennas, their distances were around 15 m each. Algorithm for solution of system of hyperbolic equations was created to determine position of signal source which is the intersection point of the hyperbolas. Position of signal source and its accuracy were graphically expressed.
