Summary:The problem of determining the distance from an arbitrary point to the center of interference band with a known profile from the data distorted by random noise is formulated. At the final stage in the developed algorithm, the Wiener–Kolmogorov filtering is used. The numerical simulation shows that the averaged error of estimate computed by the proposed method is 50–75% less than the estimate obtained without noise. The results of processing experimental data also confirm the efficiency of the proposed method.
