Abstract

The performance of target detection based on hyperspectral imaging is dependent on the spatial resolution of the imaging sensor. To investigate this dependence, we study a specially prepared scene containing a large number of simple, homogeneous targets in varying sizes. The scene is imaged from the air at a high spatial resolution using the ASI hyperspectral camera. Images corresponding to lower spatial resolutions are synthesized from the recorded data. Targets are detected using spectral anomaly detection based on Gaussian mixture distribution models. The target detection performance is compared between targets of different sizes in images of varying spatial resolution. The results indicate that the spatial resolution of a hyperspectral target detection system should be chosen just high enough to ensure that pure target pixels are present in the image data.
