CSFRT: Cross‐Spectral Feature‐Refined Transformer for Hyperspectral Image Classification

Xin Wang, Chen Gao, Dejiang Wang, Jingwen Yan

ABSTRACT Hyperspectral images (HSIs) contain rich spectral information, which enables accurate target classification. However, HSIs also contain a significant amount of redundant spectral information, and the spectra of different objects often overlap. This overlap in spectral features increases the similarity between different …

Generalized Expression for TP-CFAR Model in Point Target Detection of Subpixel Imaging

Mingyang Ma, Dejiang Wang

The two-parameter constant false alarm rate (TP-CFAR) detector is an important research direction for infrared (IR) point target detection. The traditional pixel-level TP-CFAR has great shortcomings in keeping a high detection probability for subpixel imaging targets. We establish a discretized imaging model …

Optimal Coplanar Sensor Placement Based on AOA Measurements

Kang Xu, Yu Shao, Guanbing Bai, Mingyang Ma et autres

Optimizing sensor-target geometry is an effective way to improve target localization accuracy. When localization in three-dimensional (3D) space, the geometry between the sensors lying in the same horizontal plane and the target is constrained. Based on the angle-of-arrival (AOA) localization model, this …
