Aerial imaging reconnaissance is the important means to obtain tactical intelligence. This paper designs an all-time optical aerial imaging reconnaissance system for UAV referred to various flying environment. Based on UAV(Unmanned Aerial Vehicle)mathematics model, visible camera geometry imaging model and atmospheric transmission model, the system simulates the aerial camera reconnaissance using different parameters, which are changed along with UAV motion parameters, camera imaging parameters, atmospheric transferring parameters. Numbers of test results prove that the imaging reconnaissance system has very high fidelity and validity. According to output reports, system performance can be easy to evaluate and improve. More important is that this system can help guide and demonstrate aerial imaging reconnaissance equipment for UAV.
