This Master Thesis covers the design and construction of a simulation model for a specific radar system. With this model, a complete evaluation of the entire radar system is feasible and thereby a thorough examination of the systems capabilities. The Thesis also investigates unknown characteristica of some radar components, e.g. the pulse compression modulation and the non-linearity of the Travelling Wave Tube (TWT)-amplifier. The model is developed by theoretical analysis, evaluation of the specific radar schematics and examination of some radar hardware measurements. The simulation model is implemented in Matlab and is designed with a main program calling specific coded functions. The result of the investigation of the radar components shows that a pulse compression system with a non-linear frequency modulation shaped as a 7th order Taylor pattern agrees very well with the hardware measurements. Moreover, the non-linearity of the TWT-amplifier is identified and its distortion
