Radar is described as the ability to identify radio waves to determine the range, angle and relative velocity of objects. In modern vehicle safety systems, radar is used in conjunction with cameras, ultrasound and other sensors to obtain information about the environment of a vehicle. The goal is an improved object identification, which should lead to a simplified decision making for the driver.
There are three main types of radar technology used, which differ mainly in distance of the measurement range:
With an increasing degree of automation, the number of radar sensors required in a vehicle increases significantly for reasons of redundancy and measurement accuracy. These include services such as distance warning systems, blind spot detection, stop-and-go functionality, automatic speed regulation and lane departure warning systems. These applications use different frequency ranges:
* phased out by 2022
For most countries, the scheme is divided in the two frequency bands 76 – 77 GHz and 77 – 81 GHz.
Exception: In 2017, the FCC homogenized the frequency regulation for both areas and is therefore one step ahead of many countries.
It should also be mentioned that the regulation for the frequency range 24.25 GHz to 26.65 GHz expires in 2022. The regulation for the band 24.05 GHz – 24.25 GHz, on the other hand, is already almost completely homogenized.
In our accredited laboratories, we offer test services for automotive radar technology and test the following contents, among others, in accordance with the specified specifications:
Our test reports are recognized worldwide and can be used for marketing approval in Europe, USA, Canada and Japan. However, our service portfolio is not limited to the above country requirements. Our testing services in our ISO 17025 accredited laboratories include regulatory radar testing for a variety of international certification schemes based on various test specifications and standards.
