摘要:
为了准确地预测气象雷达使用寿命, 提高气象雷达运行可靠性、安全性和可维护性, 提出了一种新的基于多元回归的气象雷达使用寿命预测框架。在该框架内,采用了支持向量 回归(SVR)方法来求解气象雷达使用寿命的多元回归问题;提出了基于SVR的气象雷达特征参 数选择FSSSVR(Feature Subset Selection SVR)算法去掉冗余和无效的特征参数。实验结 果表明,基于SVR方法的预测算法能够准确地预测气象雷达的使用寿命,能够为雷达全寿命 周期管理提供参考依据。

Abstract:
In order to accurately predict the life of weather radar and improve its r eliability, security, maintainability, a novel framework for pr edicting weather radar′s life is proposed, which is based on multiple regressio n method.Within the framework, Support Vector Regression (SVR) is induced to sol ve the multivariate regression problem of weather radar′s life, and then, a fe ature subset selection SVR(FSSSVR) algorithm is developed to remove redundant an d ineffective components of characteristic parameters. Finally, simulation results demonstrate that SVRbased prediction algorithm is able to accurately forecast the life of weather radar, and provide reference for full lifecycle management of weather radar.
