The PhD thesis deals with the topic of thermal radiation in the microwave region of the electromagnetic spectrum in the field of automatic fire detection. The thesis shows that it is possible to detect fires by their thermal radiation in the microwave region and that the thermal radiation of different fire materials depend on the observed frequency, so that it is possible to distinguish the fire materials. The thesis contains the physical basics of thermal radiation, especially in the microwave region. It further describes the developed measuring device that is able to measure the power of the thermal radiation in the frequency range between 2 GHz and 40 GHz, the setup for the standardized test fires according to EN54 and the measuring results.
