Switchable Copula-guided Transformer diffusion model for detecting small sea-surface targets
Chao Yu, Xuanzhu Sheng, Zhennian Luan, Shengyong Li
Abstract Detecting low, slow and small maritime targets remains difficult because sea clutter is non-uniform, non-stationary, non-Gaussian and often observed at extremely low signal-to-clutter ratios. Here we present a switchable Copula-guided Transformer denoising diffusion prob…
