Abstract
There are provided systems and methods for adjusting the tilt of a radar cover in response to change of weather condition by calculating dielectric constant of external air, optimum thickness of radar cover, and then optimum tilt angle of radar cover, and adjusting the position of the radar cover.
Claims8
A radar system for a vehicle, comprising:
- a radar;
- a radar cover mounted on a front surface of the radar;
- an actuator connected to the radar cover for adjusting a tilt angle of the radar cover;
- a terminal device provided with a part of the vehicle for detecting information on external weather conditions;
- and
- a controller connected to the actuator for determining, based on the weather information received from the terminal device, an optimum tilt angle of the radar cover that can minimize attenuation of a radar wave caused by the radar cover, and operating the actuator to adjust the position of the radar cover so as to realize the optimum tilt angle.
