Multi-faceted Graph Attention Network for Radar Target Recognition in Heterogeneous Radar Network
, 2022 Radar target recognition (RTR), as a key technology of intelligent radar systems, has been well investigated. Accurate RTR at low signal-to-noise ratios (SNRs) still remains an open challenge. Most existing methods are based on a single radar or the homogeneous radar network, which do not fully exploit frequency-dimensional information.
