    Specific Emitter Identification Method for Limited Samples via Time–Wavelet Spectrum Consistency by Chunyang Tang, Jing Lian, Li Zheng, Rui Gao

    Published 2025-01-01
    “…Then, we use complex-valued neural networks (CVNNs) and deep convolutional neural networks (DCNNs) to extract the hidden emitter identity features from the time and wavelet spectrum samples. We train the model using the normalized temperature-scaled cross-entropy (NT-Xent) loss and cross-entropy (CE) loss, ensuring the consistency of feature vector distributions across the two modalities with cosine loss. …”
