In this research project, we have developed a sensor model for the Navys HYDICE system, using current engineering specifications and data from Hughes Danbury Optical Systems, the manufacturer. This sensor imaging model has been integrated into an end-to-end simulation system, Multispectral Image Simulator MIS. Using MIS with the HYDICE model we have investigated Signal-to Noise Ratios SNRs that might be expected from HYDICE under low radiance conditions, such as images of coastal water areas. The results are presented in Section 4.1. We also used the Cuprite, Nevada, AVIRIS database developed earlier, for simulation of natural HYDICE imagery. This is presented in Section 4.2. Finally, we have also initiated investigation of large view angle effects on image contrast, using the Advanced Very High Resolution Radiometer AVHRR module in MIS since it allows a range of 55 deg in view angle cross-track. These simulation results are presented in Section 4.3.
