前回までに得られている物標データと今回得られた物標データとが同一の物標によるものであるとの連続性判定を行なう手段と、
連続性判定の結果、同一の物標によるものと判定された物標データについてフィルタ演算を行なう手段とを具備し、
該フィルタ演算手段は、今回の物標データが今回得られた実測値から算出されたものであり、かつ、前回の物標データが実測値ではなく外挿により算出されたものであるとき、物標データに含まれる物標の相対速度についてフィルタ演算を行なわないことを特徴とするレーダのデータ処理装置。Means for determining continuity that the target data obtained up to the previous time and the target data obtained this time are from the same target;
Means for performing a filter operation on target data determined to be based on the same target as a result of continuity determination;
The filter calculating means is configured such that when the current target data is calculated from the actual measurement value obtained this time, and the previous target data is not an actual measurement value but calculated by extrapolation, A radar data processing apparatus characterized by not performing a filter operation on the relative speed of a target included in the target data. 前回までに得られている物標データと今回得られた物標データとが同一の物標によるものであるとの連続性判定を行なうステップと、A step of performing continuity determination that the target data obtained up to the previous time and the target data obtained this time are from the same target;
連続性判定の結果、同一の物標によるものと判定された物標データについてフィルタ演算を行なうステップとを具備し、A step of performing a filter operation on target data determined to be based on the same target as a result of continuity determination,
該フィルタ演算ステップは、今回の物標データが今回得られた実測値から算出されたものであり、かつ前回の物標データが実測値ではなく外挿により算出されたものであるとき、物標データに含まれる物標の相対速度についてフィルタ演算を行なわないことを特徴とするレーダのデータ処理方法。The filter calculation step is performed when the target data of this time is calculated from the actual measurement value obtained this time, and the target data of the previous time is not an actual measurement value but calculated by extrapolation. A radar data processing method, wherein no filter operation is performed on the relative speed of a target contained in data.
