PROBLEM TO BE SOLVED: To provide a technique which settles a correct combination as pair data even in the case of the existence of a plurality of pieces of target data.SOLUTION: A radar device sets a prediction area in each of an UP section and a DOWN section on the basis of a prediction position of target data in current processing, which is derived from target data in past processing, and determines whether a plurality of pieces of target data in the current processing exist within the prediction area in at least one section or not. If a plurality of pieces of target data in the current processing exist within the prediction area in at least one section, the radar device performs settlement pairing of combining a plurality of patterns between target data in the UP section and target data in the DOWN section and settling the most probable combination as pair data. Therefore, even when a plurality of pieces of target data exist within the prediction area, the radar device can settle a correct combination as pair data and can derive a position where an object actually exists.

    【課題】複数の物標データが存在する場合でも正しい組合せをペアデータとして確定する技術を提供する。【解決手段】レーダ装置は、UP区間およびDOWN区間のそれぞれで、過去処理の物標データにより導出される今回処理の物標データの予測位置に基づき予測領域を設定し、少なくとも一方の区間の予測領域内に、今回処理の物標データが複数存在するか否かを判定する。そして少なくとも一方の区間の予測領域内に、今回処理の前記物標データが複数存在する場合に、レーダ装置はUP区間およびDOWN区間の物標データ同士で複数パターンの組合せを行い、最も確からしい組合せをペアデータとして確定する確定ペアリングを行う。これによりレーダ装置は、予測領域内に複数の物標データが存在する場合でも正しい組合せをペアデータとして確定でき、物体が実際に存在する位置を導出できる。【選択図】図1
