Resolution enhancement for hyperspectral data of China´s first lunar orbiter Chang´e-I

China´s first lunar orbiter Chang´e-1 (CE-1) has the capability to concurrently capture hyperspectral imagery with resolution of 200 m along with CCD imagery with a higher resolution of 120 m. To better serve for future lunar terrain exploration, and preparation work for the landing of probe vehicle, resolution of hyperspectral images from CE-1 needs to be enhanced. In order to make use of information from a high-resolution CCD sensor, this paper introduces a resolution enhancing method combining MAP estimation with SMM, and develops an iteration optimization algorithm and a Possion optimization algorithm. Through a set of experiments, it is demonstrated that the proposed method is more effective for practical use compared with conventional methods in resolution enhancement of hyperspectral imageries of CE-1.
