Why does the front radar beep when there's nothing in front?

[DiGage]

The reasons why the front radar beeps when there's nothing in front are: 1. The sensor hole is too small or too tight, or it is installed on an iron or hard guardrail; 2. There are attachments such as snow or ice on the painted surface of the sensor; 3. The sensor characteristics are poor, and the working environment temperature is too low; 4. The sensor is faulty. Solutions: 1. Check if there is any foreign matter on the radar electric eye, clean it, and try again; 2. Check if the electric eye is damaged or deformed, and replace the sensor if necessary. The full name of the reversing radar is reversing anti-collision radar, also known as a parking assist device. It is a safety assist device for parking or reversing a car, consisting of ultrasonic sensors (commonly known as probes), controllers, and displays (or buzzers). It can inform the driver of the surrounding obstacles through sound or more intuitive display, relieving the driver's troubles when parking, reversing, and starting the vehicle, and helping the driver eliminate blind spots and blurred vision defects, thereby improving driving safety.
