The present invention relates to a system and method for detecting the presence and/or absence of a dynamic object in a detection area, and more particularly, to a system for detecting a dynamic object, which is provided in an autonomous movable device to reduce shadow areas. The system for detecting a dynamic object includes a transceiver including a transmitter and a receiver, a storage unit storing a received radio signal, a control unit determining that the dynamic object is present in the detection area if the periodicity of the signal is observed, and a driving unit controlling the autonomous movable device.COPYRIGHT KIPO 2017본 발명은 탐지 영역 내 동적 객체의 존재 및/또는 진입 여부를 탐지하기 위한 시스템 및 방법에 관한 것으로서, 보다 상세하게는 자율 이동 장치에 구비되어 음영 지역을 줄일 수 있는 동적 객체 탐지 시스템에 관한 것이다.
