Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes a model-based motion detection method with low computational complexity that mitigates device-induced errors and is suitable for outdoor environments. The proposed approach exploits propagation conditions with limited multipath, which are typically considered unfavorable. We demonstrate through theory and experiments that the method can detect birds flying outside the line-of-sight between transmitting and receiving antennas. Experiments were conducted using beamforming feedback (BFF) from IEEE 802.11ac-compliant commercial WLAN devices, mainly targeting wild crows in an outdoor field. Results also show that vegetation-induced disturbances are negligible when wind speeds are below 3 m/s.
