Title:
COVER FOR RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/053229
Kind Code:
A1
Abstract:
The present disclosure provides a cover for a radar device, said cover being positioned so as to cover an array antenna of the radar device, and having a flat section that has a flat surface shape and a curved section that is curved in a curved surface shape, wherein the cover makes it possible for the radar device to more accurately estimate an arrival angle. A cover C1 for a radar device comprises a path adjustment section PA1 that is positioned on the path of radar waves passing through a curved section 142 and arriving at an array antenna, said radar waves being among radar waves that were emitted from the array antenna and reflected by an object. At least one of the thickness and the relative permittivity of the path adjustment section PA1 is changed so as to reduce estimation error for the arrival angle of the radar waves that pass through the the curved section 142 and arrive at the array antenna.
