The dependence of the accuracy of measuring the phase shift and amplitude of the sum signal and the error in determining the distance of objects in the application of multi-frequency phase method of measuring distances are researched. It was proposed the analytical expressions taking into account the distribution function of measurement errors. The development of the simulation algorithm was shown. It was shows the distribution function of distances of objects in view of errors in measuring the phase shift and the amplitude of the sum signal.
