仿真模型验证是从模型预期使用的角度出发,确定模型和有关数据代表真实世界正确程度的过程,是VV&A工作的重要内容之一。针对传统验证方法不能将仿真数据和试验数据的时频域特性结合起来综合分析的特点,从时频联合分析的思想出发,将Gabor变换引入仿真模型验证中,实现了对仿真数据和试验数据时频域的综合分析。实例分析表明,该方法可以提高模型验证的准确性,具有一定的实用性。

Simulation model validation is the process of determining correctness of model and relevant data representing the real world from the perspective of the intended use of the model, it is also an important part of VV&A. Since classic methods can not achieve comprehensive analysis of relevant data between time domain and frequency domain, so Gabor transform was introduced for simulation model validation and the comprehensive analysis based on time-frequency domain was achieved. The simulation analysis shows that the given method can improve accuracy of the model validation and has certain practicality.
