【課題】ペアリングの妥当性を判定する技術を提供する。【解決手段】レーダ装置は、所定周期で周波数が変わる送信信号と、該送信信号に基づく送信波の物標からの反射波を受信した受信信号との差分周波数を示すピーク信号を、送信信号の周波数が上昇するアップ区間と、周波数が下降するダウン区間とで導出し、両区間におけるピーク信号を組合せの信頼度に基づいてペアリングすることで、ピーク信号に係る物標に関する情報を取得する。そしてレーダ装置は、最も高い信頼度を示す第1指標と、該第1指標よりも低い信頼度を示す第2指標とを導出し、第1指標と第2指標との比較結果に基づき、最も高い信頼度の組み合わせの妥当性を判定する。これによりレーダ装置は、複数の組合せの信頼度の比較結果に応じて、組合せの妥当性を判定でき、正しい組み合わせのペアデータを取得できる。【選択図】図2

    A radar apparatus pairs an angle peak of an up section in which a frequency of a transmission signal increases and an angle peak of a down section in which the frequency of the transmission signal decreases based on a reliability of a pair. The radar apparatus derives a first index that shows a highest level of the reliability of a pair in a plurality of pairs of the angle peaks and a second index that shows another level of the reliability of another pair, the second index being lower than the first index in the reliability but being higher than other indexes excluding the first index, and also determines a validity of the pair having the highest level of the reliability based on a comparison result between the first index and the second index.
