The AFIT Sensor and Scene Emulation Tool (ASSET) is a physics-based model used to generate synthetic data sets of wide field-of-view (WFOV) electro-optical and infrared (EO/IR) sensors with realistic radiometric properties, noise characteristics, and sensor artifacts. This effort evaluates the use of Convolutional Neural Networks (CNNS) trained on samples of real space-based hyperspectral data paired with panchromatic imagery as a method of generating synthetic hyperspectral reflectance data from wide-band imagery inputs to improve the radiometric accuracy of ASSET. Further, the effort demonstrates how these updates will improve ASSET’s radiometric accuracy through comparisons to NASA’s moderate resolution imaging spectroradiometer (MODIS). In order to place the development of synthetic hyperspectral reflectance data in context, the scene generation process implemented in ASSET is also presented in detail.
