| 摘 要： | 仿真模型的正确与否决定着仿真的精度和置信度，而仿真模型验证是保证仿真模型正确的有效手段。现代谱估计方法对窗口以外的行为进行合理假设，克服了古典谱估计方法的缺点，相对于古典谱估计方法有优势。重点介绍了最大熵谱估计方法的基本原理以及在飞行器仿真模型验证中的应用，并举例予以说明。

| Abstract: | Accuracy and fidelity of simulation are decided by whether simulation model is correct or not. Validation of simulation model is an effective means guaranteeing that simulation model is correct. Modern spectral estimation method overcomes the disadvantage of classical spectral estimation method by adopting reasonable hypothesis about behavior of data out of window. Modern spectral estimation method has the advantage of classical spectral estimation method. The basic principle of maximum entropy spectral estimation method and its application on validation of simulation model of an aircraft is emphatically introduced. An example is given to explain how to use the method. |
