  • Radar apparatus in which the direction of the antenna is recognizable from outside
    Patent number: 6744399
    Abstract: A radar apparatus is provided in which an antenna axis and vehicle axis can agree with each other even when the antenna face is covered with a cover. In an assembling process of the radar apparatus composed of a chassis, an antenna incorporated in the chassis and a cover attached to the chassis to cover the antenna, a correlative positional relation between an antenna axis of the antenna incorporated into the chassis and one portion of the chassis or bracket is detected, and the thus detected data is inscribed on a seal and the seal is stuck to the chassis or the data is stored in an internal memory, and the chassis into which the antenna is incorporated is covered with the cover, so that the radar apparatus is manufactured. When this radar apparatus is attached to a vehicle, the antenna axis can be adjusted parallel to the vehicle axis by utilizing data of a correlative positional relation between the antenna and one portion of the chassis or bracket.
