频谱分析方法在仿真可信性研究中的应用

Application of Spectrum Analysis in the Research of Simulation Model Credibility

应用频谱分析方法进行仿真可信性评估。分析了傅立叶谱估计、最大熵谱估计的统计特性，并分别构造相容性检验。引入瞬时谱估计分析非平稳随机信号，以及应用于某型近炸引信数字仿真模型验证的一个实例。

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.
