Factorized discriminative conditional variational auto-encoder for radar HRRP target recognition.

•A method for radar HRRP target recognition is proposed based on Conditional VAE.•The model is regularized through the average HRRP for robust representations.•The label information is introduced by a three-way weight conditional model.•Weight factorization is utilized to effectively reduce model parameters.•Our method performs well under the low SNR and small amount of training data.
