Title:
RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/171828
Kind Code:
A1
Abstract:
Provided is a radar device capable of appropriately pairing arrival angles in a first direction and arrival angles in a second direction and specifying the two-dimensional directions of each of a plurality of objects. In this radar device, a plurality of antenna elements are aligned in a left-right direction (first direction) and up-down direction (second direction). A CPU of a control unit calculates the individual arrival angles in an arrival angle group for the left-right direction on the basis of reflected waves received by the plurality of antenna elements aligned in the left-right direction. The CPU of the control unit calculates the individual arrival angles in an arrival angle group for the up-down direction on the basis of reflected waves received by the plurality of antenna elements aligned in the up-down direction. According to the combination of the number of left-right direction arrival angles (incoming waves) and up-down direction arrival angles (incoming waves), the CPU of the control unit selects a method for pairing the arrival angles in the arrival angle group for the left-right direction and the arrival angles in the arrival angle group for the up-down direction (S340, S360, S370).
