Integration of automotive radar modules behind vehicle bumpers introduces losses due to the bumper's curvature, dielectric properties, and reflective paint materials. These losses distort the radar module's radiation patterns and reduce field intensity, compromising the radar's performance.
The invention pertains to a method and electronic device designed to create a non-uniformly thick matching layer for 3D components in vehicles, such as bumpers, that house radar modules. This matching layer aims to minimize the reflection and losses of microwaves caused by the bumper's curvature and materials. The method involves using a binomial matching layer technique to design this layer based on the thickness and dielectric properties of the 3D component.
- Generation of a non-uniformly thick matching layer based on the 3D component's thickness and dielectric constant.
- Use of a binomial matching layer technique to optimize the matching layer's effectiveness.
- Consideration of parameters such as impedance, load, and free space impedance.
- Representation of the 3D component surface using triangles in a 3D Cartesian Coordinate System for precise modeling.
- Reduces microwave reflections and integration losses for radar modules placed behind vehicle bumpers.
- Enhances the performance of radar modules by maintaining the integrity of their radiation patterns.
- Adapts to the non-uniform thickness of the 3D component, providing a tailored solution that addresses specific design and material challenges.
The prototype would involve an electronic device equipped with a processor, memory, radar module, and a 3D layer designing tool. This device would receive the design of a non-uniformly thick 3D component, determine its thickness at various locations, and generate a corresponding binomial matching layer to optimize radar performance.
