For many applications, ultrasonic is an excellent choice, but there are situations in which radar offers real added value. Whether for distance measurement, object detection or level determination, radar is reliable and versatile.
The technology works in almost all weather conditions, has a wide measurement range, and consumes little energy. This makes radar a smart choice for machine manufacturers looking for durable and efficient sensor solutions. You can read below why radar is becoming more common in the agribusiness sector.
1. Measurement in certain weather conditions and dirty environments
One of the biggest advantages of radar is its robustness in various weather conditions. Rain, snow or fog have little effect on performance. Dirt and contamination also have little effect because radar signals have a high penetrating power; they simply see through them. This means that such a sensor can be placed behind a protective cover, if necessary. For example, if a robot is equipped with a radar sensor so that it can navigate a barn, a user can sweep away the accumulated dirt much more easily.
2. Seeing through crops (or other objects)
The penetrating power of radar offers important advantages. A radar sensor can take measurements through obstacles such as crops, making it suitable for measuring the distance to the ground, for example. That only works with radar. An additional advantage in this case is that a radar sensor can also record speeds. This makes it possible to accurately monitor and anticipate movements.
3. Measuring long distances
Radar has an enormous range. Radar signals can easily span kilometers. Everyone is familiar with the radar systems that can detect aircraft or boats at long distances, for example, but smaller radar solutions can also span long distances.
In addition, radar is suitable for measuring short distances. This has everything to do with the speed of the radar signals: The radar receives a reflected signal at the speed of light. So fast, in fact, that the system must react at lightning speed to keep up with the signals. This can mean that the measurements are not 100% accurate at very close range. But with a precision of 2 to 3 millimeters, radar is often suitable even then.
4. When lifespan is an important factor
A radar sensor has no moving parts. As a result, it is not prone to wear and tear and lasts a long time.
5. A battery that will last for years
The lack of moving parts also ensures low power consumption. A battery-powered radar system in a feed silo, for example, can easily last 10 years.
Integrating radar: where to start?
Radar offers many benefits, but integration requires some attention. Think about technical choices, sensor placement, and regulations you need to comply with. If you follow these steps carefully, you’ll get the most out of the technology.
