| Sumario: | This thesis is focused around an existing ground based Geosynchronous Equatorial Orbit (GEO) satellite system. The group of researches that maintains this project is devoted to study the feasibility and develop different techniques that will allow the formation of Synthetic Aperture Radar (SAR) images from GEO satellites. The goal of this thesis is to study the effects and implications of orbital tracking errors in the generation of GEO SAR images. In order to achieve this, a detailed study of orbital models and orbital reference systems is presented. Additionally, a classical estimation theory has been used in order to estimate and generate realistic orbits with the capabilities of being able to be altered on demand (in order to test orbital errors). In order to simulate the effects and implications of orbital tracking errors, a ground based GEO SAR simulator has been created. The implementation of the simulator uses Object-Oriented Programming, estimation theory techniques and special SAR techniques in order to provide a robust, portable and structured simulated virtual environment that suits all the testing requirements. |
