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.
