Abstract
A radar system with angle error determination function and method thereof are provided. The system includes a camera device, a radar device, a calculation module, and an angle calibration module. The camera device captures a surveillance image of a surveillance area. The radar device sends a radar signal toward the surveillance area. The calculation module, according to the surveillance image, acquires an image angle of an object with respect to the vehicle in the surveillance area. Also, the calculation module acquires a radar angle of the object with respect to the vehicle which is produced according to a reflection signal generated when the radar signal meets the object. The angle calibration module, by referring to the image angle, correspondingly calibrates the radar angle. Therefore, the radar angle is immediately calibrated.
