Challenge

Current radar sensors used in vehicles have limited resolution, making it difficult for them to distinguish objects close to each other, potentially causing serious accidents. 

To significantly enhance resolution, the operating frequency of standard vehicle radar sensors was increased from 24 GHz with 200 MHz bandwidth to 76-81 GHz approximately 5 years ago. It is expected to be further increased beyond 100 GHz.

The new system will provide a highly detailed image of the environment in a wide field of view that can detect obstacles on the side of the road and smaller targets like a bike or a person, even if they are slightly covered by a larger object like a tree trunk.

 

Solution

The project will provide a solid foundation for silicon-based transmitter design with beam-steering capability beyond 100GHz in a cost-effective silicon-based technology. The current operating frequency of radar systems is 76-81 GHz with 200MHz bandwidth.

The project will also address the fundamental design methodology for an ultra-high-resolution wireless sensing system.

Ultimately, this project will support the development of cost-effective, fully autonomous vehicles and reduce car accidents.
