Abstract	The article is devoted to the researches the accuracy of the measurement of range by the multifrequency phase method. The sources of error of probing signals are identified in the paper. These include: instability of frequency probing signal, error of measurement amplitude and phase shift of the total reflected signals. There; was shown influence on total reflected signal. Also, when calculating the distances to objects, the condition number of matrix system of linear equations has a significant impact on the accuracy of measuring distances. The resulting graphs after mathematical modeling showed that the least impact on the accuracy occurs when frequency range of the probing signal is conformed with the amplitudefrequency response of the total reflected signal.
