Document Type and Number:
Japanese Patent JP6643203
Kind Code:
B2
Abstract:
A radar apparatus that detects an object using radiated waves includes: an antenna surface that includes an element unit that emits a radiated wave for a radar; and a cover member that covers the antenna surface to protect the element unit. The cover member includes an inner refractive surface that is an inner side surface of the cover member on which an undesired wave is incident and is formed into a shape that refracts the undesired wave incident on the inner refractive surface so as to advance towards antenna rear. The antenna rear is a side opposite an antenna front that is a side on which the radiated wave is emitted, with the antenna surface as a boundary. Undesired waves are radiated waves that are emitted outside a range of a predetermined solid angle relative to a normal direction of the antenna surface from a center of the antenna surface from which the radiated waves are emitted.
