摘　　要：借助于试验设计和响应面近似模型技术,提出了一种红外干扰弹设计方法。其基本思想是首先选取影响导弹脱靶距离的设计变量,用试验设计方法在设计变量空间里选取样本点,对各样本点进行导弹脱靶距离的计算,得到各样本点的响应值(最大脱靶距离),用这些样本点和响应值建立导弹最大脱靶距离的响应面近似模型,并对近似模型进行优化获得最优解。算例表明得到的响应面模型精度很高,可以快速得到最优解。A method for infrared flare design based on design of experiment（DOE） and response surface model（RSM） technologies is proposed.Its main idea is that the design variables that influence miss distance the missile are firstly chosen,and then the miss distance is calculated by the computer program with the samples created in the variable space with the DOE.At last,the RSM of miss distance using these samples and responses is built.Additionally,the optimal design result for the infrared flare is obtained from RSM.The example shows that the RSM model precision is hight,at the same time,the optimum can be got quickly.
