- 目標からのレーダ反射波の振幅成分、距離成分、及びドップラ周波数成分の各成分を含むレーダビデオ信号を、距離軸、ドップラ周波数軸、及び振幅軸からなる3次元空間にマッピングするとともに、前記振幅軸に対して複数の異なるしきい値を設け、それぞれのしきい値に対して前記距離−ドップラ周波数軸の2次元面において前記目標が検出されたセルとその周辺のセル群を、前記レーダビデオ信号の特徴信号として抽出する信号検出部と、
前記特徴信号の前記ドップラ周波数成分及びその周期性、ならびに前記距離成分及びその変化を含む特徴量を取得する信号特徴量取得部と、
目標の種別及び状態を含む目標の属性情報に対応させて、あらかじめその前記特徴量が蓄積された目標情報データベースと、
前記信号特徴量取得部で抽出した特徴量に基づいて前記目標情報データベースを検索し、前記目標の種類及び状態を特定して類別する目標類別部と、
前記類別結果を所定のリストに編集して出力する類別結果編集部と
を備えたことを特徴とするレーダ信号処理装置。 - 前記信号検出部における振幅軸に対するしきい値は、あらかじめ設定された観測時間内において所定の時定数で変化させることを特徴とする請求項1に記載のレーダ信号処理装置。
