Document Type and Number:
WIPO Patent Application WO/2023/282132
Kind Code:
A1
Abstract:
Provided are a radar device capable of distinguishing between a plurality of stationary target objects existing in similar positions, and precisely measuring the azimuth of each target object, without being affected by cross-correlation components between each received signal, and a vehicle provided with said radar device. An FMCW radar device 1 includes a radar module 11 and a vibrating body 13. An actuator 13a that initiates vibrations having a magnitude less than a distance resolution of the radar device 1 is used as an example of the vibrating body 13. A shielding case 10 is supported by a bracket 9, by way of fixing portions 14. The fixing portions 14 comprise a resilient material, the shielding case 10 vibrates irregularly in conjunction with the vibration of the actuator 13a, and the vibrations of the shielding case 10 are transmitted to a circuit board 11a. A pattern constituting an array antenna 3 is formed on a top surface of the circuit board 11a, and an electronic component 11b constituting the radar module 11 is mounted on a rear surface thereof.
