Title:
RADAR DEVICE, PROCESSING DEVICE, CALCULATION METHOD, AND CALCULATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/014686
Kind Code:
A1
Abstract:
A radar device according to the present invention comprises: a first antenna array comprising a plurality of antennas disposed on a first straight line; a second antenna array comprising a plurality of antennas disposed on a second straight line orthogonal to the first straight line; and a calculation unit that calculates a two-dimensional arrival bearing of one or a plurality of incoming waves on the basis of a received value for a signal received by the plurality of antennas included in the first antenna array and a received value for a signal received by the plurality of antennas included in the second antenna array. The shortest distance among the distances between the plurality of antennas included in the first antenna array and the plurality of antennas included in the second antenna array is greater than the antenna spacing of the first antenna array or the second antenna array.
