Experimental Evaluation of 79 GHz Radar Performance in Fire Environments

This paper experimentally proves the ability of millimetre wave radar to provide visibility of objects in a fire. The operation of an imaging radar at a frequency of 79 GHz was investigated under various real conditions, including fire with strong flame, dense smoke, and water vapour. Absorption of the radar signal was measured and the results are in accordance with theoretical calculations. The analysis of the experimental results allows us to conclude that there are good prospects for millimetre wave radar in the field of firefighting equipment for vision and navigation.
