New method for determination of dynamic characteristics of dissipative systems according to instantaneous values of damped oscillations trace is considered. The method is based on computation of root-men-square estimations for coefficients of linear parametrical discrete model in the form of stochastic difference equation. Results of numerically-analytical investigations of suggested method effectiveness are provided. Computations inaccuracy can be decreased by order in comparison with well-known method for definition oscillation decrement by using amplitude envelope curve.
