PROBLEM TO BE SOLVED: To improve the estimation accuracy of the locus of a target.SOLUTION: The locus estimation device of the present invention includes an acquisition unit and an analysis unit. On the basis of the frequency spectrum of a sensor signal acquired from a sensor, the acquisition unit acquires the distribution of a plurality of points to be observed in a prescribed space and the amplitude values corresponding to respective points to be observed. The analysis unit applies a regression analysis using the weights of the points to be observed that are determined on the basis of the amplitude values to the distribution of the points to be observed in the prescribed space, and acquires, as a locus of a target, a functional model acquired by the regression analysis.SELECTED DRAWING: Figure 1

    【課題】物標の軌跡の推定精度を向上させること。【解決手段】本発明に係る軌跡推定装置は、センサから得られたセンサ信号の周波数スペクトルに基づいて、所定空間における複数の被観測点により構成される上記被観測点の分布およびにより上記被観測点ごとに対応する振幅値を取得する取得部と、上記所定空間における上記被観測点の分布について、上記振幅値に基づいて決定される上記被観測点ごとの重みを用いた回帰分析を行い、当該回帰分析により得られる関数モデルを物標の軌跡として取得する分析部と、を備える。【選択図】図1
