Title:
DIRECTION-OF-ARRIVAL ESTIMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/240632
Kind Code:
A1
Abstract:
This direction-of-arrival estimation device is characterized by comprising: a speed information acquisition unit that acquires speed information of a target; a transmission unit that transmits radio waves; a receiving antenna that receives reflected waves of said radio waves, the reflected waves coming from the target; and a direction-of-arrival estimation unit that estimates the direction of arrival of the reflected waves received by the receiving antenna, by using the target speed information acquired by the speed information acquisition unit. The present disclosure makes it possible to estimate the direction of arrival of the reflected waves from the target, with an accuracy higher than the estimation accuracy possible with the prior art.
