| Abstract: | The method of simulating radar correlated clutter and the characteristics of its AR spectrum model are presented. A modified Levinson algorithm with constraint conditions and its AR model orders estimating method are proposed, and the estimated result of the model orders of the common Gaussain spectrum characteristics and the simulated results are given. These results are compared with the estimated results of Burg algorithm under the same condition. The useful conclusion is drawn, and one of its applica- tions, i. e realization of digital signal source is described briefly. |
