Title:
RADAR DEVICE AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/074949
Kind Code:
A1
Abstract:
In the present invention, an antenna device has first and second radiation patterns that are different from each other. The first radiation pattern has a main lobe, and a side lobe having a first gain. The second radiation pattern has a main lobe, and a side lobe having a second gain different from the first gain. A signal analyzer detects a first signal level of radar waves received when the antenna device was set to the first radiation pattern and detects a second signal level of radar waves received when the antenna device was set to the second radiation pattern. An obstacle identifier determines that a reflecting object is an obstacle when the difference between the first and second signal levels is smaller than a threshold and otherwise determines that the reflecting object is not an obstacle.
