Title:
RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/286483
Kind Code:
A1
Abstract:
In a radar device according to the present invention, a plurality of transmission antennas or a plurality of reception antennas includes a first antenna group disposed in a first direction and a second antenna group disposed in a second direction differing from the first direction, and the remaining other from among the plurality of transmission antennas and the plurality of reception antennas includes a third antenna group disposed in a third direction, which differs from both the first direction and the second direction, where the interval between adjacent antennas is an interval of greater than or equal to one wavelength of a transmission signal.
