The integration of radar presents technical and regulatory challenges. What should be considered?
Legislation and regulations
When integrating a radar sensor, it's important to pay close attention to the frequency band in which it operates. Because radar is an electromagnetic RF signal, it can cause interference with other signals, such as the 5G Wi-Fi band. Radar is therefore subject to all sorts of restrictions, which often differ per country or region.
In England, for example, radar sensors are not allowed to operate in the 24 GHz band because it is reserved for the police, who use it for speed enforcement. And in the US, 60 GHz is permitted, but only if the signals travel vertically, as otherwise it could interfere with data communication. Therefore, it is allowed on a spray boom because the signal is directed at the ground. However, it is not allowed if such a construction can fold its arms and the signal is transmitted horizontally. System builders who want to sell their products worldwide will therefore have to comply with all regulations.
Recognize reflections
Beyond legislation and regulations, integrating radar sensors is not always technically straightforward. Unlike the sound waves of an ultrasonic sensor, the RF radio signal from a radar has high penetration power. This allows a radar sensor to see through objects and detect objects behind them, which is often very useful, but it also means it receives multiple reflections. Furthermore, some materials are permeable to radar, resulting in a weak reflection. The challenge lies in selecting the correct reflection(s) from all these signals. A skilled radar specialist can help OEMs with proper target selection.
