Situational Awareness for Emergency Services

Radar works when you need it most: in fire, smoke and hot gases when other sensors don’t.

Navtech radars deliver uninterrupted performance in fire, smoke and hot gases. How can we achieve this? Radar is ‘self-illuminating’, that’s a way to say it’s an active sensor that sends out its own signal into the environment, and receives it back in order to gather information about its surroundings. In contrast, visual cameras and thermal sensors are passive. A camera relies on light in the environment for object detection, and therefore it can’t see through thick smoke. A thermal sensor relies on the heat signature of objects in the environment for detection, and so it cannot differentiate between objects in the hot conditions produced by a tunnel fire.
