Terahertz Radar: A New Era in Auto Safety under any weather conditions, night and day

To have more than one kind of sensor on a car and not to relay on a single kind of sensor is probably a good idea! Unfortunately, this complicates things.

"... conditions that render nearly all of today’s car-mounted sensors useless: fog and bright early-morning sunshine. Radar can’t see small objects well, lidar is limited by fog, and cameras are blinded by glare. Carey and his cofounders decided to create a sensor that could have done the job—a terahertz imager. ...

But thanks to some intense engineering and improvements in silicon transistor frequency, beaming terahertz radiation over hundreds of meters is now possible. Teradar, the Boston-based startup Carey cofounded, has managed to make a sensor that can meet the auto industry’s 300-meter distance requirements. ..."
