Radar integration presents technical and regulatory challenges. What do you need to consider?
Legislation and regulations
When integrating a radar sensor, it is important to pay close attention to the frequency bandwidth in which it operates. Because radar is an electromagnetic RF signal, it can cause interference to other signals, such as the 5G Wi-Fi bandwidth. Radar is therefore subject to a variety of restrictions, which often vary by country or region.
In England, for example, radar sensors are not allowed to operate in the 24 GHz bandwidth because this is reserved for the police who use it to carry out speed checks. And in the US, 60 GHz is allowed, but only if the signals travel vertically, otherwise they can interfere with data communications. It is therefore permitted on a spraying boom, for example, because the signal is only aimed at the ground. But it is not allowed if the equipment can fold its arms and the signal is transmitted horizontally. System builders who want to market their products worldwide therefore have to properly comply with all regulations.
Recognizing reflections
Apart from the aforementioned legislation and regulations, the integration of radar sensors is also not always technically straightforward. Unlike the sound waves from an ultrasonic sensor, a radar's RF radio signal has high penetrating power. This enables a radar sensor to see through objects and recognize objects behind other objects, which can be very useful, but it also means that it receives multiple reflections. In addition, some materials are permeable to radar, creating a weak reflection. The trick is to select the right reflection(s) from all those signals. A knowledgeable radar specialist can help OEMs with the correct target selection.
