| 摘 要： | 雷达系统仿真模型复杂、计算量大,是导弹攻防对抗仿真实验复杂度的主要组成部分。为了降低仿真实验的复杂度,依据雷达系统工作原理,为雷达系统仿真模型构建了四种形式的元模型:线性元模型、多项式元模型、径向基函数元模型和Krging元模型。通过实验比较看出,二阶多项式元模型具有拟合精度高、计算速度快、模型简洁等特点。在攻防对抗仿真中用它代替雷达系统仿真模型,可以大大提高仿真实验的效率。

| Abstract: | The complexity and large calculating quantity of radar system simulation model is a main part of missile combat simulation experiment complexity. In order to reduce the complexity of simulation experiment, based on working principle of radar system, four simulation metamodels for radar system simulation model were built, which include linear metamodel, polynomial metamodel, radial basis function metamodel and Kriging metamodel. Through comparisons of experiments, the polynomial metamodel has proved to have characteristics of high fitting precision, rapid calculation and concision. As substitute for radar system simulation model, it will increase the efficiency of simulation experiment. |
