WIPO Patent Application WO/2019/039517
Kind Code:
A1
Abstract:
This radar device is provided with an antenna unit, a power supply unit for supplying power to the antenna unit, a dielectric member (21) provided such that waves emitted from the antenna unit pass therethrough, and a filter unit (20) which is provided on the dielectric member (21). The filter unit (20) is provided with multiple band transmission sections (30, 40, 50) arranged along a scanning direction. The band transmission sections (30, 40, 50) each transmits radio waves of different transmission frequency bands. The power supply unit sequentially switches the frequency of the radio waves emitted from the antenna unit to a frequency within a configured emission band included in each of the transmission frequency bands.
