| Abstract: | In this paper, spectrum estimation is applied to study the credibility of simulation. the statistical properties of Fourier spectrum estimation and MESA are analyzed respectively, and both consistence tests are presented. Wigner distribution is introduced to analyze non stationary signal, and an application example of validating the simulation model of a proximity fuze is given. |
