Why does the front radar keep beeping on rainy days?

[Stella]

There are several reasons why the front radar keeps beeping on rainy days: 1. Heavy rain: Continuous rain lines may be detected as obstacles by the front radar. If the obstacle distance is less than a certain value, such as 0.35 meters, the radar will emit a continuous alarm, which is a normal phenomenon. 2. Light rain: The radar may also emit a continuous alarm during car washing. This is usually caused by water forming a medium on the surface of the probe, which increases the detection angle. It may detect the ground (if the probe is installed at a low height or angled downward) or objects on the vehicle body such as license plates, trailer poles, or spare tires, leading to false alarms. This is normal and can be avoided by adjusting the direction or position of the probe or obstacles on the vehicle body. 3. Defect: If the probe has inherent defects, it may need to be repaired or replaced.
