Abstract

In order to validate the performance of data processing algorithms cheaply and efficiently, imaging simulation is significant. This pa per discusses an imaging simulation method for space-based optical sensors which have wide field of vision and scanning mechanisms. To avoid background’s saltation and to make simulation real, the proposed method uses the data from Moderate-resolution Imaging Spectroradiometer (MODIS) as original input. Pre-treatments for MODIS data including periodic extension are applied to enlarge the background. Then scan-line sensor is modelled and ray tracing method is used. Typical effects resulting from the sun and detectors are considered. Finally, imaging simulation results indicates that images produced by this method are logical and can be applied to validate data processing algorithms.
