Zusammenfassung:	To distinguish a moving target from a stationary target in detecting the moving target, and reduce a calculation load, a storage load, and a consumption load.SOLUTION: A target detector 1 includes: a beat signal acquisition unit 11 for acquiring a beat signal between sending-receiving signals of an FMCW radar; a differential signal calculation unit 12 for calculating a differential signal between beat signals with different sending-receiving cycles; and a moving target detection unit 13 for detecting the presence of a moving target in a detection distance range when the intensity of the differential signal is at least a predetermined signal intensity, and detecting the absence of a moving target in the detection distance range when the intensity of the differential signal is lower than the predetermined signal intensity.SELECTED DRAWING: Figure 1 【課題】本開示は、移動物標を検知するにあたり、移動物標を静止物標と区別し、計算負荷、記憶容量及び消費電力を低減することを目的とする。【解決手段】本開示は、ＦＭＣＷレーダの送受信信号間のビート信号を取得するビート信号取得部１１と、異なる送受信周期のビート信号間の差分信号を算出する差分信号算出部１２と、差分信号の強度が所定信号強度以上であるときに、検知距離範囲内に移動物標が存在することを検知し、差分信号の強度が所定信号強度より低いときに、検知距離範囲内に移動物標が存在しないことを検知する移動物標検知部１３と、を備えることを特徴とする物標検知装置１である。【選択図】図１
