A Multi-Modal Fusion Algorithm for Space Target Recognition Based on Spatial Attention and Multi-Scale Temporal Network

Aerospace
When fusing inverse synthetic aperture radar (ISAR) images and high-resolution range profile (HRRP), the significant heterogeneity existing between the feature spaces of the two is not adequately considered, resulting in a low accuracy rate of space ...

Frequency Estimation Using Complex-Valued Shifted Window Transformer

, 2023
Estimating closely spaced frequency components of a signal is a fundamental problem in statistical signal processing. In this letter, we introduce 1-D real-valued and complex-valued shifted window (Swin) transformers, referred to as SwinFreq and ...
