この発明(ま光検知並びに電波探知併用の空中線装置の
改良に関する。DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in an antenna device that uses both optical detection and radio wave detection.
即ち、従来から遠方の目標物を検知し、その目標物の移
動を追跡あるいは誘導するのにレーザ光並びにレーダ波
を併用する装置が知られている。That is, devices have been known that use both laser light and radar waves to detect a distant target and track or guide the movement of the target.
レーザ光は比較的近距離目標の精密な検知並びに追尾に
有効であり、一方レーダ波は広域の空間を捜索し目標を
検知あるいは追尾に適する特徴がある。Laser light is effective for precise detection and tracking of targets at relatively short distances, while radar waves are suitable for searching a wide area of space and detecting or tracking targets.
レーザ光並びにレーダ波を併用できる装置はそれぞれ両
者の特徴を選択的に使用できる利点がある。Devices that can use both laser light and radar waves have the advantage of being able to selectively use the characteristics of both.
従来の送受信装置はレーダ機能をはだすものとしてパラ
ボラアンテナ等を採用した構成を主体とし、これにレー
ザ受光系あるいはレーザ送受光系を付加する形状がとら
れている。Conventional transmitting/receiving devices mainly have a configuration employing a parabolic antenna or the like to provide a radar function, and have a configuration in which a laser receiving system or a laser transmitting/receiving system is added to this.
しかしながら、同時使用を可能とする目的の上から1.
レーダ系統は同一機械軸上に位置することが必要である
が、従来の導波管やホーンアンテナ並びにパラボラ形ネ
射器を使用するレーダ構成では、どこにレーザ受光系を
設けるかが問題であり、周波数帯域を全く異にする両系
酵を並立させることの弊害が多かった。However, for the purpose of enabling simultaneous use, 1.
The radar system must be located on the same mechanical axis, but in conventional radar configurations that use waveguides, horn antennas, and parabolic radiators, the problem is where to install the laser receiving system. There were many disadvantages to having both types of fermentation, which have completely different frequency bands, running side by side.
例えば機械的な位置関係から、し二ダ空中線を光学系に
並用するため、レーダ空中線反射器の面精度や方位角制
御に対して必要以上の精煕が、要求されたり、光検知器
をレーダ送信電力から効果的に遮蔽できないこと等であ
る。For example, due to the mechanical positional relationship, since a secondary antenna is also used in the optical system, more precision than necessary is required for the surface accuracy and azimuth control of the radar antenna reflector, or the photodetector is For example, it cannot be effectively shielded from transmitted power.
そこで、本発明装置は、構成が簡単にして、レーダ系統
並びにレーザ等の光学系稗を、相互の不要な干渉を最小
にし、しかも、同時使用並びに切換使用にも好適な送信

以上本発明の一実施例を第1図ないし第2図を参照して
説明する。An embodiment of the present invention will be described above with reference to FIGS. 1 and 2.
第1図は本発明装置の一実施例を示す。FIG. 1 shows an embodiment of the apparatus of the present invention.
。即ち、遠方からの到来光をいわゆるカセグレン形受光
器からなる実光器1を備え、この集光器1で集光された
光を光検知器2で検知する。. That is, a real light device 1 consisting of a so-called Cassegrain type light receiver is provided to receive light arriving from a distance, and a photodetector 2 detects the light collected by this light collector 1.
集光器1は、先端に設けた副反射器11と副反射器11
に到来光を反射供給する主反射器12とから構成される
。The condenser 1 includes a sub-reflector 11 and a sub-reflector 11 provided at the tip.
The main reflector 12 reflects and supplies incoming light to the main reflector 12.
ところで、光検知器2は前記集光器1と共に支柱3等に
より一体化されて設けられ、これが第1の駆動部4の前
方に位置しこれがこの第1の駆動部4によって到来光の
方向を軸として回転駆動されるよう構成される。By the way, the photodetector 2 is provided integrally with the light condenser 1 by a support 3 or the like, and is located in front of the first drive section 4, which directs the direction of the incoming light. It is configured to be rotationally driven as a shaft.
前記第1の駆動部4は後述するレーダ用副反射器5の背
面に固定されるようになっており、レーダー送信電力を
直接受けないような大きさのものである。The first drive section 4 is fixed to the back surface of a radar sub-reflector 5, which will be described later, and is sized so as not to directly receive radar transmission power.
前記光検知器2は、集光器1から入射する到来光を受け
、光を検知するに十分な大きさのもので、特にレーダー
送信電力により焼損されないように第1の駆動部4より
もやや小形でその前方に位置しているものである。The photodetector 2 is large enough to receive and detect the incoming light incident from the condenser 1, and is slightly larger than the first drive unit 4 so as not to be burned out by the radar transmission power. It is small and located in front of it.
6はレーダー用主反射器で、この前方に多数の支柱3・
・・を介して前記副反射器5が設けられる。6 is the main reflector for the radar, and in front of it are many pillars 3 and 3.
The sub-reflector 5 is provided through...
7はホーンアンテナで、前記主反射器6及び副反射器5
を介して電波を送・受信するようになりいわゆるカセグ
レンアンテナを構成する。7 is a horn antenna, which includes the main reflector 6 and the sub-reflector 5;
It transmits and receives radio waves through the antenna, forming a so-called Cassegrain antenna.
8はこれら主反射器6及び副反射器5を前記した軸を中
心に回転させる他の支柱3・・・を介して設けられる第
2の駆動部である。Reference numeral 8 denotes a second driving section provided via other supports 3 for rotating the main reflector 6 and the sub-reflector 5 around the above-mentioned axis.
なお、前記第1及び第2の駆動部4及び8を回転駆動す
るについては、ミサイルなどにおいて周知のようにレー
ダ系及び光学系については、送信電波の周波数などの関
係から、例えば1800RPM〜3600 RPMで回
転させつつ、電波及び光を発信し、それぞれの受信情報
により目標物を追尾することができるようになっている
ものである。In addition, regarding the rotational driving of the first and second driving units 4 and 8, as is well known in missiles, etc., the radar system and optical system may be rotated at, for example, 1800 RPM to 3600 RPM due to the frequency of the transmitted radio waves. It transmits radio waves and light while rotating, and can track a target based on the information received from each.
このように本発明の空中線装置は、周知の回転可能なカ
セグレンアンテナの副反射器5の背面に、これまた回転
可能な光受光系を備えたもので、この結果レーダ系も光
学系も共に同一回転軸上に位置し、しかも光学系はそれ
独自で、また回転可能な構成となり互いに独立して作動
し得る作用を持つものである。In this way, the antenna device of the present invention is equipped with a light receiving system that is also rotatable on the back side of the sub-reflector 5 of the well-known rotatable Cassegrain antenna, and as a result, both the radar system and the optical system are the same. Located on the rotation axis, the optical system has its own independent and rotatable structure, and has functions that allow it to operate independently of each other.
従って、光学系はレーダ系の副反射器5の背面にあるか
ら、直接レーダ送信波の影響を受けることなく、しかも
レーダ系と同一軸上にあって独立した回転駆動をなすも
ので、レーダ系の広域捜索と光学系の近距離追尾とが互
いに独立に動作させ得るし、互いに同一軸上にあるから
同一目標物に対してはレーダ系から光学系へあるいは逆
に光学系からレーダ系への連繋動作が可能である。Therefore, since the optical system is located on the back side of the sub-reflector 5 of the radar system, it is not directly affected by the radar transmission waves, and is on the same axis as the radar system and rotates independently. The wide-area search by the optical system and the short-range tracking by the optical system can be operated independently of each other, and since they are on the same axis, the same target can be operated from the radar system to the optical system, or conversely from the optical system to the radar system. Linked operation is possible.
第2図は本発明による他の実施例で、第1図と同一構成
には同一符号を付して詳細な説明を省略する。FIG. 2 shows another embodiment of the present invention, in which the same components as those in FIG. 1 are given the same reference numerals and detailed explanations are omitted.
即ち、到来光を受光する集光器1を有し、集光器1から
の光を検知する検知器2と共に駆動部4によって一体回
転駆動される。That is, it has a condenser 1 that receives incoming light, and is rotated integrally with a detector 2 that detects the light from the condenser 1 by a driving section 4.
駆動部4はレーダ用平面アンテナ9の中心に固定され、
アンテナ駆動部8の回転駆動によって前記集光器1等の
光学系と共に回転制御される。The drive unit 4 is fixed at the center of the radar planar antenna 9,
The rotation of the antenna driving section 8 together with the optical system such as the condenser 1 is controlled.
平面アンテナ9は例えば多数のダイポールアンテナを平
面状に配列した構成にするか、あるいは導体からなる箱
体の前面に多数のスリットを設は輻射するいわゆる開口
面アンテナで構成することができる。The planar antenna 9 may be constructed by arranging a large number of dipole antennas in a planar shape, or may be constructed from a so-called aperture antenna that radiates light by providing a large number of slits in the front surface of a box made of a conductor.
また平面アンテナ9からレーダ波を送出する場合には、
アンテナから所定のレーダビームを形成させるためあら
かじめ位相制御されて、信号あるいは電力分配された信
号が平面アンテナ9に供給される。In addition, when transmitting radar waves from the planar antenna 9,
In order to form a predetermined radar beam from the antenna, the phase is controlled in advance and a signal or a power-divided signal is supplied to the planar antenna 9 .
平面アンテナ9はある角度範囲内においては電子走査ア
ンテナとしてビームを走査させることが可能であるから
、用途によってアンテナ駆動部8を設けずにすますこと
もできる。Since the planar antenna 9 can scan the beam as an electronic scanning antenna within a certain angle range, the antenna driving section 8 can be omitted depending on the application.
なお第1図に示した装置も第2図に示したように本発明
装置を覆うレドーム10を取着して使用できる。Note that the device shown in FIG. 1 can also be used by attaching a radome 10 covering the device of the present invention as shown in FIG.
また、第2図に示す装置では、光学系は第1図の場合と
同じであるもののレーダー系は相違し、光学系がレーダ
系の前方をさえぎる形をなすから、光学系の径dを大き
くとることはできないが、通常レーダアンテナ径りに対
してd/D<0.2を満たす場合であれば実用上支障が
ないことがわかった。In addition, in the device shown in Figure 2, the optical system is the same as in Figure 1, but the radar system is different, and the optical system blocks the front of the radar system, so the diameter d of the optical system is increased. However, it was found that there is no practical problem as long as d/D<0.2 is satisfied for the radius of the radar antenna.
