Quasi-optimal estimation of distance and velocity using laser ranging

An algorithm for estimation of distance and velocity using laser ranging in each repetition period of the sounding train of optical pulses is synthesized. It is demonstrated that the algorithm allows a simpler technical implementation in comparison with the maximum-likelihood algorithm. The characteristics of estimations are found with allowance for anomalous errors. Accuracy loss of quasi-optimal estimations is determined in comparison with the maximum-likelihood estimations. Methods of statistical simulation are used to demonstrate the efficiency of the synthesized algorithm and the applicability limits are determined for the asymptotic formulas that make it possible to determine the characteristics.
