Why does the reversing radar beep?

[Gonzalez]

If the reversing radar beeps as soon as you reverse, it is likely due to a faulty radar. It is recommended to visit a repair shop for a detailed inspection. Additional relevant information is as follows: 1. Low obstacles: Generally, obstacles that are 10~15cm below the center of the probe may be overlooked by the probe. The closer the obstacle is to the vehicle, the lower this height threshold becomes, increasing the risk. 2. Thin obstacles: Due to the narrow ultrasonic signals emitted by the radar probe, there are significant blind spots when detecting thin obstacles. Road isolation poles and diagonal steel cables on utility poles are potential hazards. 3. Trench radar: The trench radar is used to detect obstacles. If there is a trench behind the vehicle, the radar will not respond.
