| Abstract: | Form the point of view of processing the signal detected by the fuze system , multiform power spectrum estimate methods are introduced in brief. Theory, method and application of modem power spectrum estimate are analyzed in detail. The processing course of AR power spectrum estimate method which is classic method in parameter model power spectrum estimate method and the course of MUSIC power spectrum estimate method and the eigenvector method which are classic methods in non-parameter model power spectrum estimate method are discussed. These power spectrum estimate methods are compared. In the end the advantage of processing the signal detected by fuze system is explained. |
