Usually, the ADAS system senses the surrounding situation through the camera or radar installed on the car so as to play the role of each ADAS system. In order to ensure that these ADAS systems can function properly, in some cases, we need to calibrate the camera and radar systems to ensure the safety of the car and driver! Today, let's learn about automotive radar calibration!
Car radar calibration refers to the process of adjusting and verifying the accuracy of a radar system installed on a vehicle. Typically, car radar systems use radio waves and sensors to detect objects, pedestrians, vehicles, and obstacles around the vehicle. To ensure that the measurements and calculations performed by these systems are accurate and reliable, radar systems need to be calibrated.
Although owning a car, most people are full of doubts about car radar calibration: does radar need calibration?
The answer is Yes. We have listed several reasons why a radar system must be calibrated:
① Safety: Radar systems are applied to automotive ADAS systems and are directly related to safety. Inaccurate radar measurements can feed wrong information back to the driver, which could lead to accidents or danger.
② Accuracy: Calibration ensures that distance, speed and angle are accurate and consistent with actual values. This accuracy is critical to making informed decisions and taking appropriate actions based on radar data.
③ Environmental impact: Harsh environmental conditions will affect the performance of the radar. Calibration can help identify and correct data errors and avoid traffic accidents.
④ Component variability: The radar system is completed by various components, and slight changes in the manufacturing process may cause performance differences. Calibration helps account for these variations and ensures consistent results.
⑤ Wear: Over time, the components of a radar system may experience wear, affecting performance.
⑦ System changes: If the radar system is repaired, replaced, or parts replaced, it needs to be recalibrated to ensure accuracy.
The accuracy of radar systems is critical to automotive safety. Proper and regular calibration helps maintain the integrity of these measurements and ensures that the radar system performs as intended.
When the situation mentioned above occurs, radar calibration can be performed. Usually, in order to ensure our driving safety, regular calibration and maintenance of the car radar system is carried out at the suggestion of the car manufacturer or technician.
The process of automotive radar calibration includes the following:
① Initial Calibration: When a radar-equipped vehicle is manufactured, the radar sensors are calibrated to ensure they are properly aligned and configured according to the vehicle's specifications.
② Installation and calibration: If the repair or maintenance of the vehicle involves the removal or replacement of radar components, the radar system needs to be recalibrated to ensure the accuracy of the data.
③ Dynamic Calibration: Calibrate the radar sensor when the vehicle is moving to ensure that the radar measurement can accurately reflect the vehicle's position, direction and speed.
④ Static Calibration: Some radar systems need to be calibrated when the vehicle is stationary. This may involve aligning the radar sensor with a specific target at a known distance.
⑤ Target board and tools: Calibration may involve the use of specialized target boards, reflectors, or other tools placed at specific distances and angles around the vehicle. These tools help radar sensors detect and measure accurately.
⑥ Software update: Sometimes radar calibration requires a software update to the vehicle's on-board computer system. These updates improve the performance and accuracy of radar-based features.
⑦ Validation and testing: After calibration, the radar system is tested to ensure it correctly recognizes objects, calculates distance and provides accurate data for ADAS functions.
