What is the sound when hitting the radar?

[AugustLynn]

Radar emits a continuous beep when hitting an obstacle. Here are the relevant details: 1. Reversing Radar: The reversing radar, also known as "reverse anti-collision radar" or "parking assist device", mainly consists of ultrasonic sensors, a controller, and a display. 2. Working Principle: When reversing, the reversing radar uses the ultrasonic principle. The probe installed on the rear bumper sends ultrasonic waves that reflect off obstacles, calculates the actual distance between the vehicle body and the obstacle, and then alerts the driver, making parking or reversing easier and safer.

I know a bit about radar systems. They use ultrasonic sensors on the bumper to measure distance, beeping every time you reverse. As you slowly approach an obstacle, the sound frequency changes from a relaxed 'beep—beep—beep' to a rapid 'beepbeepbeepbeep.' If you actually hit something, it suddenly turns into a continuous loud 'beeeeep—' or a wailing siren-like alert, strongly urging you to stop. Some cars also flash dashboard icons to help you see the situation behind. To prevent malfunctions, I often clean the sensors to avoid mud blockages; I also pay attention to sound changes and don’t rely solely on the beeping while ignoring my actual view.

Every day when I drive home and back into the parking space, the radar beeps softly in my ear. At first, it's an intermittent 'beep-beep', which turns into a frantic 'beepbeepbeep' as the distance closes. Once, when I was too flustered, I scraped the garage wall, and the radar immediately emitted a sharp, continuous 'wuuuu' sound, startling me into slamming on the brakes. The sound design is quite clever—using gentle tones for safe distances and harsh, sustained signals to force action during collisions. But don't rely on it too much; occasionally, dirty sensors can give false alarms, so I have to check the rearview mirror from time to time.

The radar warning function is a lifesaver for collision prevention. Normally, it detects obstacles and emits intermittent 'beep' sounds, with the rhythm speeding up as the distance decreases. Upon actual contact, the tone changes to a straight, prolonged 'woo—' sound as a warning of contact. This mechanism helps prevent accidents from escalating. Regular cleaning of the sensors is necessary to avoid dirt affecting sensitivity. Simple maintenance can save you a lot of trouble.
