Description

この発明は、電波源目標を探知して、電波源目標に向かって飛しょうする誘導飛しょう体に関するものである。   The present invention relates to a guided vehicle that detects a radio wave source target and flies toward the radio wave source target.

従来の電波源対応の誘導飛しょう体は、電波の到来方向を捉え、電波源方向に向かって誘導飛しょうする。電波源目標であるレーダには、デコイおよびレーダ装置を用いて、飛しょう体方向へのレーダ装置の電波の送信を停止し、デコイの電波を送信することにより、飛しょう体の捉える電波の到来方向を誤らせ、レーダと離隔した安全な場所に誘導させる等の対抗方式を得る様々な提案がなされている。一例として、複数のデコイを運用し、アクティブフェーズドアレイアンテナを有するレーダ装置がビームのヌルを飛しょう体に向ける従来技術が知られている(例えば、特許文献1参照。)。   The conventional flying object corresponding to the radio wave source captures the direction of arrival of the radio wave and guides it toward the radio wave source. For the radar that is the radio wave source target, the decoy and radar device are used to stop the transmission of the radar device's radio wave in the direction of the flying object, and the decoy's radio wave is transmitted, so the arrival of the radio wave that the flying object captures Various proposals have been made to obtain countermeasures such as misdirection and guidance to a safe place separated from the radar. As an example, a conventional technique is known in which a radar apparatus using a plurality of decoys and having an active phased array antenna directs a beam null toward a flying object (see, for example, Patent Document 1).

特開2001−59865号公報(第7−9頁、第1図)Japanese Patent Laid-Open No. 2001-59865 (page 7-9, FIG. 1)

電波源対応の誘導飛しょう体は、電波の到来方向を捉え、電波源方向に向かって誘導飛しょうする。これに対し電波源目標であるレーダは、デコイおよびレーダ装置を用いて、飛しょう体方向へのレーダ装置の電波の送信を停止し、デコイの電波を送信する対抗手段をとることにより、飛しょう体の捉える電波の到来方向を誤らせ、レーダと離隔した安全な場所に誘導されてしまう問題があった。   The guided flying object corresponding to the radio wave source captures the arrival direction of the radio wave and guides it toward the radio wave source. On the other hand, the radar that is the radio wave source target uses the decoy and the radar device to stop the transmission of the radar device's radio wave in the direction of the flying object and take the countermeasure by transmitting the decoy's radio wave. There was a problem that the direction of arrival of radio waves captured by the body was misguided and guided to a safe place separated from the radar.

係る課題を解決するために、デコイの影響により発生するレーダの送信停止方向を避け、レーダが送信を継続している方向へ飛しょうするため、再度レーダの送信電波を捉えることが可能となり、目標に対しより高い精度で会合することを目的としている。   To solve the problem, the radar transmission direction is avoided by avoiding the direction of the radar transmission stop caused by the decoy, and it is possible to capture the radar transmission radio wave again. The purpose is to meet with higher accuracy.

この発明の誘導飛しょう体は、目標を追尾し目標方向を得る追尾装置と、飛しょう体の位置、速度、加速度、姿勢角、姿勢角速度の運動情報を得る慣性装置と、目標の位置情報を算出し、目標の真偽を判定し、目標が偽と判定した場合には目標を再度捕捉できるように経由点を算出し、目標に向かって飛しょうするための加速度指令を算出する誘導演算部と、上記誘導演算部で算出された加速度指令を処理して飛しょう体の運動を制御するオートパイロットと、を備え、上記誘導演算部として、追尾装置で得られた目標方向を慣性装置で得られた飛しょう***置を原点に換算し、地形高度線との交点を算出することにより、目標の位置情報を算出し、次に、過去に算出された目標の位置情報と現在の目標の位置情報との差により、目標の真偽を判定し、目標が偽と判定した場合には真目標を再度捕捉できるように偽目標を追尾装置の視野外に入れるように、飛しょう体の経由点を算出する目標情報処理部と、目標情報処理部からの飛しょう体の経由点から加速度指令を算出する加速度指令演算部を備えたものである。 The guided flying object of the present invention includes a tracking device that tracks a target and obtains a target direction, an inertial device that obtains movement information of the flying object's position, velocity, acceleration, posture angle, and posture angular velocity, and target position information. Calculate, determine the true / false of the target, and if the target is determined to be false, calculate the waypoint so that the target can be captured again and calculate the acceleration command to fly toward the target And an autopilot that controls the movement of the flying object by processing the acceleration command calculated by the guidance calculation unit, and the inertial device obtains the target direction obtained by the tracking device as the guidance calculation unit. The target position information is calculated by converting the obtained flying object position to the origin and calculating the intersection with the topographic altitude line, and then the target position information calculated in the past and the current target position The truth of the target due to the difference with the information A target information processing unit that calculates the waypoint of the flying object so that the false target is placed outside the field of view of the tracking device so that the true target can be captured again if the target is determined to be false, and target information An acceleration command calculation unit that calculates an acceleration command from a transit point of the flying object from the processing unit is provided.

この発明によれば、追尾装置の捉えた目標を位置移動量によりレーダかデコイかを判定し、デコイである場合には、デコイを避ける経由点を算出し、飛しょう体の運動を制御するため、デコイの影響、レーダの送信停止方向を避け、レーダが送信を継続している方向から飛しょうするため、再度レーダの送信電波を捉えることが可能となり、目標に対しより高い精度で会合することができる。   According to the present invention, it is determined whether the target captured by the tracking device is a radar or a decoy based on the amount of position movement. If the target is a decoy, a via point that avoids the decoy is calculated and the movement of the flying object is controlled. In order to avoid the influence of decoy and the direction in which radar transmission is stopped and to fly from the direction in which the radar is continuing to transmit, it is possible to capture the radar's transmitted radio wave again and meet with higher accuracy to the target Can do.
