FCC Certification for Automatic Parking Radar Sensors

With the rapid development of intelligent driving technology, automatic parking systems have gradually become a standard configuration in modern automobiles. One of the core components enabling precise parking functionality is the millimeter-wave radar sensor. By transmitting and receiving high-frequency electromagnetic waves, such sensors accurately measure the distance between the vehicle and obstacles, thereby achieving safe and efficient automatic parking. However, to enter the U.S. market, automatic parking radar sensors must obtain FCC (Federal Communications Commission) certification to ensure their electromagnetic compatibility (EMC) and radio frequency (RF) compliance.

Why Does Your Radar Device Need FCC Certification?

The Federal Communications Commission (FCC) requires all radio transmitting devices sold or operated in the U.S. market to comply with its technical standards and obtain authorization. This ensures that devices do not cause harmfUL interference and can operate normally within designated frequency bands.

Automatic parking radar sensors rely on transmitting and receiving high-frequency electromagnetic waves to real-time detect the distance, angle, and speed of obstacles around the vehicle. Their operating frequencies are mostly concentrated in the 24GHz or 77GHz bands, which are strictly regulated radio spectrum resources in the United States. According to the Code of Federal Regulations (CFR) formulated by the FCC, all radio transmitting devices entering the U.S. market must pass FCC certification to demonstrate that their electromagnetic radiation meets safety standards, will not interfere with other electronic devices, and will not endanger human health. This means that even if an automatic parking radar sensor has excellent performance, it cannot be legally sold or installed in the United States without FCC certification.

Process Interpretation

During the certification process, laboratories conduct three core tests on the sensor:

①　Electromagnetic Compatibility (EMC) Test: Ensures the sensor is not interfeRED by other electronic components in complex vehicle-mounted environments.

②　Radiated Spurious Emissions Test: Strictly limits the intensity of useless signals radiated by the device to avoid affecting the normal operation of mobile phones, navigation systems, and other equipment.

③　Frequency Stability Test: Guarantees that the sensor maintains frequency accuracy under extreme working conditions such as high/low temperatures and vibrations, preventing parking judgment errors caused by frequency drift.
