Abstract
The problem of determining the distance from an arbitrary point to the center of an interference band with a known profile from data distorted by random noise is posed. The developed algorithm uses the Wiener-Kolmogorov filtering at the final stage of obtaining the estimate. Numerical simulation shows that the average error of the estimate calculated by the proposed method is smaller by 50-75% than that obtained under the assumption of no noise. The results of the experimental data processing also confirm the effectiveness of the proposed method.
