融合动态极化旋转域与状态空间模型的全极化HRRP识别
Fully polarimetric HRRP recognition based on the fusion of dynamic polarization rotation domain and state space model
摘要
Abstract
Aiming at the problems such as the easy loss of spatial topology and weak generalization of small samples in the fully polarimetric high-resolution range profile(HRRP)recognition of space targets,this paper pro-poses a novel recognition method fusing the dynamic polarization rotation domain and the state space model(SSM).The proposed method sequentially extracts polarimetric features along the spatial range dimension to con-struct a dynamic polarization rotation domain sequence,enhancing the expression of physical mechanisms while retaining the spatial topology,and then designs a dual-stream SSM with parallel physics and data to efficiently cap-ture long-range spatial dependencies through linear complexity.Experimental results based on electromagnetic simulation datasets of multi-typed typical satellites demonstrate that the proposed method outperforms benchmark methods in terms of overall recognition accuracy,achieving complementary advantages between data and mecha-nisms,and exhibits better generalization capability and robustness under the conditions of small samples and low signal-to-noise ratios.关键词
