Document Type and Number:
WIPO Patent Application WO/2020/026895
Kind Code:
A1
Abstract:
According to the present invention, two antennas receive three radio waves having different frequencies. On the basis of received signals, for the three radio waves having different frequencies, that are received by each of the two antennas, a calculation unit determines the arrival direction of the three radio waves, which propagate via two mutually differing paths from the same transmission location and arrive at the two antennas.
