Abstract:

The training process of high resolution range profile (HRRP) online recognition methods in existence usually needs large scale HRRPs, and these methods are difficult to achieve online recognition under small scale HRRPs condition. In order to deal with the online recognition issue with small scale HRRPs, an incremental support vector data description (ISVDD) algorithm is firstly developed, and then an online recognition method of HRRP for radar systems based on ISVDD is proposed. The proposed method can avoid the requirement of large scale samples in training process and achieves an excellent recognition performance. Meanwhile,since ISVDD is used to perform online recognition, compared with the online recognition method based on standard SVDD, the proposed method reduces the training time of incremental samples and can get the recognition performance as well as that of HRRP recognition in batches based on SVDD. The experimental results based on four types of planes prove the efficiency and validity of the proposed method.
