Method of Intelligent Built-in Test Failure Predication for Radar

On the basis of summarizing several kinds of common failure predication methods, the algorithm of Support Vector Regression （SVR） based on statistical theory is introdueed. To avoid the blind establishment of the parameters, this study proposes intelligent genetie algorithms for optimizing the SVR＇ s parameters and presents the process of seleeting SVR＇ s parameters particularly. Then the SVR model is applied to the radar intelligent Built-in Test failure predieation field. Finally, we adopt the intelligent Built - in Test condition monitoring data to verify the SVR model. The experimental result demonstrated that SVR model ean prediet the radar fault effeetively.
