To improve prediction accuracy of a flight track.SOLUTION: According to an embodiment, a flight track prediction device comprises: a past flight track database; a flight track pattern preparation unit; a flight pattern estimation unit; and a flight track pattern probability calculation unit. The past flight track database is configured to accumulate past flight track data including points on a past flight track of an aviation body. The flight track pattern preparation unit is configured to interpolate points of the past flight track data in accordance with the number of points, and prepare a flight track pattern by clustering a plurality of pieces of interpolated past flight track data on the basis of a distance index between the points. The flight pattern estimation unit is configured to estimate a flight track pattern of the acquired flight track data on the basis of the acquired flight track data and the prepared flight track pattern. The flight track pattern probability calculation unit is configured to calculate, as to the flight track data, a flight track pattern probability serving as an index indicative of similarity of the flight track data with respect to the estimated flight track pattern.SELECTED DRAWING: Figure 1

    【課題】 航跡の予測精度を向上させること。【解決手段】 実施形態によれば、航跡予測装置は、過去航跡データベース、航跡パターン作成部、航跡パターン推定部、航跡パターン確率算出部を具備する。過去航跡データベースは、飛行体の過去航跡上のポイントを含む過去航跡データを蓄積する。航跡パターン作成部は、ポイントの数に応じて過去航跡データのポイントを補間し、補間された複数の過去航跡データをポイント間の距離指標に基づきクラスタリングして航跡パターンを作成する。航跡パターン推定部は、取得された航跡データと、作成された航跡パターンとに基づいて、取得された航跡データの航跡パターンを推定する。航跡パターン確率算出部は、推定された航跡パターンに対する航跡データの類似性を示す指標である航跡パターン確率を、当該航跡データについて算出する。【選択図】 図1
