摘要
Abstract
A novel radiometric identification algorithm based on reconstructive dimensional reduction analysis is proposed for the applications of satellite communication security.The proposed algorithm searches the subspace which guarantees the minimum distances of intra-class feature vectors and the maximum distances of inter-class feature vectors in a supervised fashion after the extraction of the high-dimension feature vectors from all satellite devices.After the reduction of the feature vectors,the support vector machine can be trained and be used to predict the class label of an unknown device.The discriminative fingerprint features of satellite devices extracted with the proposed algorithm are linear combinations of high-dimension vectors,which reserve all the minute differences of different satellite devices.Experiments on actual data sets show the effectiveness of this algorithm for tasks of satellite devices identification.关键词
