Real-time visualisation of antenna radiation patterns

Projecte final de carrera fet en col.laboració amb el Department of Electrical and Information Technology. Lund UniversityIn this project the real-time visualisation of antenna radiation patterns through in- frared thermography is studied. This technique allows for a 2-dimensional imaging of incident power levels on the surface of a detector screen, through their temper- ature signature, thus revealing a region of the radiation pattern of the emitting antenna when placed at a distance. Based on previous experiences, the design parameters of the resistive screen on which to observe the heat signature of incident microwave radiation have been studied in detail and di®erent possible implementations have been discussed. Mod- els of the coating for the resistive screen have been made in order to test their validity for the technique under study
