This EngD project will be conducted within the MID4automotive project, see description below. In MID4automotive, a fully functional photonically integrated automotive radar prototype will be developed. The prototype will be integrated in 3D-MID technology to achieve direct integration into the car bumper, i.e. the radar will become part of the bumper rather than a module that is attached to/behind the bumper. This allows for more cost-effective solutions due to the reduction in assembly parts, construction and maintenance costs.
