PROBLEM TO BE SOLVED: To detect an unmanned aircraft by distinguishing it from other flying objects more reliably than before.SOLUTION: An unmanned aircraft detector comprises: transmission/reception means for radiating a transmission wave with a prescribed frequency into a space, receiving a reflection wave of the transmission wave, and generating a beat signal; and detection means for applying a prescribed signal process to the beat signal and thereby detecting an unmanned aircraft flying in the space. The detection means determines whether or not the beat signal includes a frequency component of a fuselage vibration specific to unmanned aircrafts, and thereby detects unmanned aircrafts.SELECTED DRAWING: Figure 1

    【課題】従来よりも確実に無人航空機を他の飛翔体と区別して検知する。【解決手段】空間に所定周波数の送信波を放射し、当該送信波の反射波を受信してビート信号を生成する送受信手段と、ビート信号に所定の信号処理を施すことにより空間に飛行する無人航空機を検知する検知手段と、を備え、検知手段は、無人航空機特有の機体振動の周波数成分がビート信号に含まれているか否かを判定することにより無人航空機を検知する。【選択図】図1
