PROBLEM TO BE SOLVED: To improve the accuracy of detecting a target.SOLUTION: The radar device according to an embodiment of the present invention is a radar device for detecting a target on the basis of a frequency-modulated transmitted wave and a reflected wave of the transmitted wave that was reflected by the target, comprising an extraction unit, a generation unit and a filter processing unit. The extraction unit extracts a peak that corresponds to the target on the basis of a beat signal that is a difference wave between the transmitted wave and the reflected wave. The generation unit generates an instantaneous value that corresponds to the peak on the basis of the peak extracted by the extraction unit. The filter processing unit applies time-series filtering to the instantaneous value generated by the generation unit and thereby generating target data that is a filter value that corresponds to the instantaneous value. The filter processing unit can also assign a plurality of instantaneous values to an assignment range that corresponds to one target data on the basis of each element included in the instantaneous value.SELECTED DRAWING: Figure 2

    【課題】物標の検出精度を向上させること。【解決手段】実施形態に係るレーダ装置は、周波数変調された送信波と物標による送信波の反射波とに基づいて物標を検出するレーダ装置であって、抽出部と、生成部と、フィルタ処理部とを備える。抽出部は、送信波と反射波との差分波であるビート信号に基づいて物標に対応するピークを抽出する。生成部は、抽出部によって抽出されたピークに基づいてピークに対応する瞬時値を生成する。フィルタ処理部は、生成部によって生成された瞬時値に対して時系列フィルタリングを施すことによって瞬時値に対応するフィルタ値である物標データを生成する。また、フィルタ処理部は、1つの物標データに対応する割り当て範囲に対し、瞬時値に含まれる各要素に基づいて複数の瞬時値を割り当て可能である。【選択図】図2
