| Abstract: | Based on the theories and methods of modern parameter spectrum evaluation, the paper assesses the spectrum values by using model parameters through time-order model and brings for- ward the ways to increase classical spectrum frequency resolution using the weighted method. This will overcome two limits of the classical spectrum evaluation and improve the quality of short order spectrum evaluation. |

| Keywords: | spectral analysis weighted method frequency resolution |
