Radar is the New Black – How it Works

RADAR – RAdio Detection And Ranging – an object-detection system that uses radio waves to determine range, altitude, direction, or in this case, speed.

Basically – a wave is sent out, it bounces off an object, returns home, and a measurement is recorded.

The car was travelling at 111 km/h.

Automakers are starting to use radar in their safety aids.

Infiniti’s Q50 uses it in its Blind Spot Intervention System.

As does Hyundai’s Genesis, which looks like this.

The radar is behind that reflective piece.

Very basically – it sends out a signal, which travels along the road, beneath the cars in front of it, up to two away, then returns. If it determines those cars ahead are slowing down, the car slows down too.

Doesn’t look like much huh, just a flat piece of plastic.
