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.

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.
