AI Technical Summary

Technical Problem

Conventional beamforming radar devices require numerous transceivers and antenna elements, leading to high cost, high power consumption, low spatial resolution, and increased computation load, which is not suitable for automotive or vehicle applications.

Method used

A radar device with a new architecture comprising a controller, radiofrequency module, waveguides, and controllable antenna modules, where the controller applies antenna parameters to each module to control electromagnetic waves, reducing the number of transceivers and enabling modular, upgradable, and reconfigurable design.

Benefits of technology

The new radar device is less costly, consumes less power, and offers improved spatial resolution with fewer transceivers, while being easily integrated and adaptable for various uses.
