Manufacture method of radar device for recognizing antenna direction from outside

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 internalmemory, 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.

Description

Method for manufacturing radar device capable of recognizing direction of antenna from outside Cross References to Related Applications This application claims priority from Japanese Patent Application No. 2002-052028 filed on February 27, 2002, the entire contents of which are hereby incorporated by reference. technical field The present invention relates to a radar device capable of recognizing the direction of an antenna from the outside, and in particular to a radar device capable of easily recognizing radio waves from the antenna from the outside even when the antenna surface is covered by a protective member such as a cover (カバ-) and cannot be seen. The radar device transmits in the direction of reception and aligns the vehicle axis with the direction of the antenna axis. Background technique In recent years, in order to prevent collision accidents between front and rear vehicles driving on the road before they happen, vehicle distance warning systems have been pu...

AI Technical Summary

Problems solved by technology

(1) When the inside of the antenna or radar is exposed, there is a risk of damage to the radar device when the radar device before measurement is installed on the vehicle

In addition, a cover for the purpose of preventing breakage is also required, requiring man-hours for assembly and disassembly.

(2) The radome of the radar device has both internal protection and airtight functions. In the method of removing the cover and adjusting the antenna shaft, it is difficult to ensure the airtightness of the product when the radome after the adjustment of the antenna shaft is installed.

(3) In the method of measuring the inclination of the antenna surface in a state where the installation positions of the antenna surface and the cover surface are correlated, in the method of mounting the radar device on a vehicle such that the installation positions of the antenna surface and the cover surface are correlated, Difficult in terms of cost and operability
