Radar equipment fault diagnosis method based on support vector domain description

To surmount the problem that radar equipment fault detection data to be hard get, support vector domain description is be used to diagnose radar fault, and have established the kind of classification model based on a classification. This model uses few fault sample and the sample under normal state to establish fault classification model, realizes the fault diagnosis of fault identification and complete radar equipment. Finally, through diagnose fault of logarithm magnifying circuit to verify the feasibility of this method, and reach a good diagnosis result.
