Abstract:

Aiming at the problem of poor target recognition of radar high-resolution range profiles (HRRP) sequences in the presence of interference or severe background clutter, a discriminative infinite fuzzy restricted Boltzmann machine (Dis-iFRBM) model is proposed. The proposed model employs a combination of two distinct machine learning techniques: discriminative restricted Boltzmann machine (Dis-RBM) classification and infinite restricted Boltzmann machine (iRBM) model complexity adaptive features. The model parameters are extended from real numbers to fuzzy parameters, drawing on the advantages of the fuzzy neural network in extracting the features more stably in a low signal-to-noise ratio environment. This approach achieves a more stable extraction of the original features of HRRP sequences as well as more robust recognition of radar targets. The recognition stability and robustness of Dis-iFRBM are validated through recognition experiments on several HRRP sequences, and the comparison experiments the proposed model and other models demonstrate the effectiveness and superiority of the proposed model in the "noisy" environment.
