A portable W band radar system for enhancement of infrared vision in fire fighting operations
In this paper, we present a millimeter wave radar system which will enhance the performance of infrared cameras used for fire fighting applications. The radar module is compact and lightweight such that the system can be combined with inertial sensors and integrated in a hand held infrared camera. This allows for precise distance measurements in harsh environmental conditions, such as tunnel or industrial fires, where optical sensors are unreliable or fail. We discuss the design of the RF front end, the antenna and a quasi optical lens for beam shaping as well as signal processing and demonstrate the performance of the system by in situ measurements in a smoke filled environment.
