Abstract

PURPOSE:To orientate the direction at night by attaching two spot light sources in a plane including the center line of a horizontal beam so that the position of one spot light source does not coincide with the center of an antenna revolving shaft. CONSTITUTION:Spot light source 3a and 3b are attached in positions in a vertical plane including the center line of the antenna horizontal beam of a reflection mirror 1 and a radiator 2, and the light source 3a is placed on an antenna revolvin shaft 4 and the light source 3b is placed apart from the shaft 4. Direction orientating glasses 5 set in a specific direction of this radar antenna to aim at light sources 3a and 3b, and the antenna is rotated and is so asjusted that light sources 3a and 3b coincide with a vertical line in glasses 5, and thereby, the direction of the center line of the antenna horizontal beam at this time coincides with the direction of glasses 5.

It can only be carried out during the day when the target in the azimuth direction can be seen, and cannot be carried out at night.
c6 [Summary of the Invention] This invention provides two point light sources in a vertical plane including the center line of the horizontal beam of a radar antenna, such that the position of at least one point light source does not overlap the center of the rotation axis of the antenna. The purpose of this radar antenna is to provide a radar antenna that can be attached to a vehicle and used to determine direction even at night.
