To obtain a radar signal processor with which it is possible to identify an object with high accuracy.SOLUTION: A primary feature quantity relating to the relative distance and relative speed of an object detected by a primary feature quantity extraction unit 11 and the azimuth and reflection intensity of the object are identified in time sequence by a data storage processing unit 12. A secondary feature quantity is extracted by a secondary feature quantity extraction unit 13. Instantaneous scores are accumulated in a cycle direction for the distribution of secondary feature quantities relating to a prescribed category having been calculated by a relatedness calculation unit 14, and the accumulated scores are calculated as cumulative scores by a cumulative/instantaneous score calculation unit 16. The category of an object is determined by an object determination unit 17 on the basis of the cumulative scores calculated by the cumulative/instantaneous score calculation unit 16.SELECTED DRAWING: Figure 1

    【課題】精度の高い物体識別を行うことができるレーダ信号処理装置を得る。【解決手段】一次特徴量抽出部11で抽出された物体との相対距離と相対速度並びに物体の方位と反射強度に関わる一次特徴量をデータ格納処理部12において時系列的に同一化を行い、二次特徴量抽出部13において二次特徴量を抽出し、帰属度算出部14で算出した所定のカテゴリに関する二次特徴量の分布に対して瞬時スコアを周期方向に累積したものを累積スコアとして累積/瞬時スコア算出部16で算出し、累積/瞬時スコア算出部16で算出された累積スコアに基づき物体判定部17で物体のカテゴリを判定する。【選択図】図1
