摘　　要：目的克服现场温度测试难以短时间内获得高温极值的缺陷,准确制定导弹导引头舱机场停放高温环境条件,提出一种导引头舱内高温预计的方法。方法在导引头舱内温度测试数据基础上,建立基于Elman网络的导引头舱温度预计模型,并与BP网络预计模型、线性网络预计模型进行对比,通过均方误差(MSE)、拟合相对误差(MRE)和最大绝对误差(MAE)等指标评估3种模型的预计能力。结果基于Elman网络的温度预计模型精度比BP网络高出约1℃,比线性网络高出约1.5℃。结论 Elman网络温度预计模型具备准确预计导引头舱内温度的能力,该方法可用于导弹停放温度预计工作,为确定导弹贮存温度环境适应性要求提供参考。The paper aims to propose a method for predicting the high temperature in the seeker cabin to solve the problem that it is difficult to obtain the high temperature extreme value in a short time in the site temperature measurement and customize the high temperature environment conditions for airplane parking of missile seeker cabin. An Elman network model for temperature prediction was established based on seeker cabin measured data. Compared with BP network model, linear network model, the prediction capacity of the three models were evaluated in terms of mean square error(MSE), mean relative error(MRE), maximum absolute error(MAE) and other indicators. The precision of temperature prediction model based on Elman network was about 1 ℃ higher than that of BP network, and was about 1.5 ℃ higher than that of linear network. Elman network temperature prediction model has the ability to accurately predict the temperature in the seeker cabin. This method can be used to predict the parking temperature of missiles. It provides reference for determining the environmental adaptability conditions of missile storage temperature.
