CD-TrGNN: A Complex-Domain Transformer–Graph Neural Network for ISAR Space Target Attitude Estimation
Yonghua He, Jiahao Wang, Aoxiang Pan, Wei Qu, Weigang Zhu, Yonggang Li, et al.
In ground-based space surveillance, space target attitude estimation is critical for space situational awareness, yet existing methods based on inverse synthetic aperture radar (ISAR) images suffer from three core limitations: phase information is discarded in amplitude-only proc…
