In order to tackle the internship challenges, I have been oriented to study different documentations describing the radar architecture, the associated simulators and finally the specifications used for the development of the different radar subsystems that will be used by the tool under developing. Simultaneously, as the subject of the study was how to simulate the effect of the solar radiation on the radar reception, I have investigated what might be the trajectories of the sun at different period of the year as well as the different solar events that could create interferences in telecommunication systems. Moreover, part of the devoted tasks was related to further software development on existing tools. In this context, I experienced slightly C language but more consistently Java. The latter was quite new to me but with the support of Thales people I have been able to acquire the possibility to understand and develop. Finally, by using the existing tools and simulators then by integrating the developed files and the achieved scenarii, it was planned to integrate them so as to obtain a simulating environment. This goal was achieved by running them manually but the final goal was to run a function which compute the solar position. As the initial study on the solar positioning and ephemerides was a bit more time consuming and considering that the engineering team oriented the investigation in a slightly different way. As a result, the management decided that the automation will be carried out by Thales team, afterwards.
