Cohda introduces new 360˚ radar for V2X connected vehicles

Cohda Wireless is introducing a low-cost, 360-degree radar for vehicles fitted with V2X connected car systems. The new V2X-Radar delivers a 360-degree sensor that can detect buildings, road signs and also older vehicles that are not equipped with V2X technology. Unlike current technologies, it is unaffected by rain, snow or fog, and can “see” around corners.

V2X-Radar takes advantage of current V2X systems that use IEEE 802.11-compliant wireless signals to share sensor information between vehicles and infrastructure. These radio signals bounce off many objects—walls, road signs and other vehicles—as they travel from transmitter to receiver. V2X-Radar can use these radio waves

Cohda’s V2X-Radar is a software application that works with standard transmissions from any V2X system, whether it’s on a vehicle or on the roadside. Compatible with both US and European standards, the V2X-Radar software only needs to be fitted in the receiving vehicle.

In combination with a 3D map, V2X-Radar provides highly accurate positioning even in urban canyons. It can instantly detect vehicle speeds via Doppler measurements and obtain 360-degree sensing from a single antenna.

Cohda Wireless CEO Dr. Paul Gray said V2X-Radar solved the chicken-or-egg problem of delivering value for drivers in the early days when V2X deployment rates are still low.

The challenge of deploying V2X is realizing clear benefits for early adopters. Cohda Wireless, a V2X pioneer, developed V2X-Radar to solve this issue for the V2X business case. V2X-Radar uses standard V2X radio signals to sense the surrounding environment, transforming a standard V2X communications system into a 360-degree car radar.

The V2X-Radar is standards-compliant, requiring no additional hardware in a V2X-equipped vehicle and no additional on-air messages, Gray said. “All it needs is our software in the receiving vehicle. V2X-Radar currently works with the NXP Roadlink chipset.

Cohda is demonstratingV2X-Radar at the ITS World Congress in Bordeaux, France, which runs from 5-9 October.



I just wonder if the increasing amount of microwave radiation in our life is good for us?


@Paroway, microwave radiation is non-ionising, so I wouldn't worry too much.
I would be more worried about being hit by a truck wule crossing the road.

Innovations like this show why Tesla won't be able to upload new software onto their cars and go fully automated, they'll need new sensing hardware.
If you can sense the road ahead and around you with inexpensive radar, it will be much easier to build fully automated driving systems.
Visual data is very hard to interpret, with shadows and variable conditions due to rain and snow, etc.


Sensors and effective vehicle guidance systems will be improved month after month.

As with aircraft pilots, even the bad human drivers will be reluctant to give up the control of their vehicle to the automated system and will probably continue to create 82+% of accidents for
many more years.
