Target detection is an important issue in hyperspectral remote sensing image processing. This paper proposes a method for hyperspectral target detection using data field theory to simulate the data interaction in hyperspectral images (HSIs). We then build a data field model to unify spectral and spatial information. Furthermore, a support vector detector based on a data field model is proposed. Compared with traditional methods, our method achieves superior performance for hyperspectral target detection, and it describes a target class with a more accurate and flexible high potential region. Moreover, in contrast to traditional hyperspectral detectors, the proposed method achieves integrated spectral–spatial target detection and shows superior robustness to signal-noise-ratio decline and spectral resolution degradation. The experimental results show that our method is more accurate and efficient for target detection problems in HSIs.
