The paper presents a new method to determine the temporal position of the received signal and the description of the mathematical apparatus method. The result of the research indicates the dependence of measurement error from the distance between the transmitter and the reflector. It is also demonstrated a comparison of the tested method with the single comparator method. Besides, according to graph data it has been inferred that the measurement accuracy of two-frequency method increased more than two times.
