【発明の詳細な説明】 ［発明の技術分野］ この発明は、移動して設置されるレーダ装置のレーダ
空中線に関し、特に特定方位方向に向けて照準する、い
わゆる方位標定に関する。Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a radar antenna of a radar device that is moved and installed, and particularly to so-called direction orientation for aiming in a specific direction.

ダ空中線を特定方位方向（例えば真北方向）の目標に向
けて照準する。[Prior Art] When a movable radar device is installed at an arbitrary location, the radar indicator (hereinafter, abbreviated as an indicator) is used to set a reference azimuth for calibrating the azimuth of a bright line. Aim the antenna toward a target in a specific azimuth direction (eg, true north direction).

以下、このことをレーダ空中線の方位標定という。 Hereinafter, this is referred to as orientation of radar antenna.

一般的なレーダ装置は、指示器の上に真北を示す直線
を、指示器ブラウン管の中心点から周辺へ向けて輝線で
表示する。A general radar device displays a straight line indicating the true north on the indicator as a bright line from the center point of the indicator CRT toward the periphery.

るので、指示器のブラウン管上に真北を示す輝線が表示
される時点で、当該レーダ空中線の水平ビームの最大強
度の方向が真北に一致していなければならない。Since the radar antenna and the sweep line of the indicator rotate in synchronization, when the bright line indicating true north is displayed on the cathode ray tube of the indicator, the direction of maximum intensity of the horizontal beam of the radar antenna is true north. Must match.

視認できる昼間に限定され、夜間に行うことは難しい。Conventionally, as a method of azimuth orientation of a radar antenna of a mobile radar device, a method of using an aiming tool for orientation (such as a gate and a star), and a method of using eyeglasses for orientation are known. Is limited during the daytime when the target object in the direction for orientation is visible, and it is difficult to perform at nighttime.

The azimuth orientation is performed even at night by performing azimuth orientation while visually observing the above two point light sources with the azimuth orientation spectacles which are installed separately from each other when viewed from the rotation axis of the radar antenna, and are installed at an appropriate distance from the radar antenna. It is an object of the present invention to provide a radar antenna that can perform the above.

FIG. 1 is a front view showing an embodiment of the present invention, and FIG. 2 is a side view of the embodiment shown in FIG.
(1) is a reflecting mirror, (2) is a radiator, (3a) and (3b) are point light sources, (4) is a rotation axis of a radar antenna, and (5) is azimuth orientation spectacles.

離れた位置に取り付けられる。The point light sources (3a) and (3b) are attached to the reflecting mirror (1) and the radiator (2) in the vertical plane including the center line of the horizontal beam of the radar antenna, and are attached to the reflecting mirror (1). The attached point light source (3a) is attached on the rotation axis (4) of the radar antenna, and the point light source (3b) is attached at a position apart from this rotation axis (4).

For example, in the case of azimuth orientation aiming the radar antenna toward the true north direction, the azimuth orientation glasses (5) are separated from the radar antenna by an appropriate distance so that the optical axis thereof faces the true south and its field of view is Point light source (3
Install so that a) and the point light source (3b) enter.

の方位標定が行えるようになる。Then, the radar antenna is rotated while looking through the azimuth orientation glasses (5), and the radar antenna is adjusted so that the two point light sources (3a) and (3b) are aligned on the vertical line. The direction of the center line of the beam coincides with true north, which enables the orientation of the radar aerial line even at night.

すなわちレーダ空中線を夜間に方位標定する場合、地
球の磁場によって動作する磁針に頼る必要がある。That is, when orienting a radar antenna at night, it is necessary to rely on a magnetic needle that operates according to the earth's magnetic field.

そして、磁針の方向を頼りに直接レーダ空中線の方位
標定を行うことも可能であるが、小さい磁針を用いて大
きなレーダ空中線を夜間、高精度に方位標定することは
極めて困難になる。Although it is possible to directly orientate the radar aerial line by relying on the direction of the magnetic needle, it becomes extremely difficult to orientate a large radar aerial line at night with high accuracy using a small magnetic needle.

従ってこの発明では、磁針の方向にその光軸を容易に
合わせられる方位標定用眼鏡（５）を用い、この光軸が
真南に向くように設置し、上述の点光源（3a），（3b）

のである。Therefore, in the present invention, the azimuth orientation glasses (5) whose optical axis can be easily aligned with the direction of the magnetic needle are used, and the azimuth orientation glasses (5) are installed so that the optical axis faces to the south, and the point light sources (3a), (3b )
Is used to determine the orientation of the radar antenna.

構成で夜間でも容易に方位標定を行うことができるよう
になる。That is, when looking at the point light sources (3a), (3b) with the azimuth orientation glasses (5) while moving the radar antenna, the point light source (3a) does not move because it is on the rotation axis (4), (3b) moves horizontally according to this rotation. When the two point light sources (3a) and (3b) coincide with each other on the vertical line in the field of view, the direction of the radar antenna coincides with the optical axis, that is, it is directed to the true north. With the configuration, orientation can be easily performed even at night.

軸４から見て離れた位置にあれば、点光源（3a）も特に
回転軸上にある必要はない。In the above-mentioned embodiment, the azimuth orientation aiming at the true north direction is explained, but it goes without saying that the orientation can be similarly carried out in any direction, and the point light source (3a) is provided on the rotation axis. It is easier to perform orientation, but if the two point light sources (3a) and (3b) are located far from the rotation axis 4 in the vertical plane including the centerline of the horizontal beam of the radar antenna, The light source (3a) also need not be on the axis of rotation.

There is an effect.
