Abstract: For intense electronic equipment in missile guidance and control systems, coupling relationship among feature parameters and low prediction accuracy of traditional least squares support vector machine(LS-SVM),the traditional LS-SVM is improved by analyzing the temporal correlation and spatial correlation of feature parameters. Traditional LS-SVM and improved LS-SVM are fused by taking advantage of D-S evidence theory. An unification of least squares support vector machine(ULS-SVM)prediction model is established. The key parameters are predicted by taking missile guidance and control systems as an example. The results show that the proposed ULS-SVM prediction model is rational and effective.
