Radar sensors

• The radar sensor measures car position and size, allowing ideal brush positioning in drive-through and tunnel car-washes.
• The sensor signal is unaffected by water spray and associated cleaning agents.

• The radar sensor measures the height of the arm relative to the ground or a corner cube.
• The sensor signal is unaffected by adverse environmental conditions.

• Precise ground distance measurement
• The measurement remains unaffected by the temperature of the air and the asphalt

• Measurement of ground and crop distance for height control
• Simultaneous measurement of the ground and plant distance allows determination of crop heights
• Quick response time

• Measurement of ground and plant distance for height control of the attachment
• Simultaneous measurement of the ground and plant distance allows determination of crop heights
• Quick response time

• Measurement of the ground distance allows a variety of applications
• Penetration depth for tillage equipment or seeding machines
• Sinking in of the tractor, slope recognition for anticipatory engine speed control

For flat objects it is very important that the tilt of the surface is not greater than half the opening angle. This is to ensure that radar beams reflected from the surface are reflected back into the sensor for proper detection. Round objects have the advantage that they are rotationally symmetric. This makes alignment much easier, as round objects always reflect something back to the sensor. Compared to a flat object with comparable size, the signal strength of the reflected  beam is reduced.

Radar beams can penetrate certain materials (such as plastic panes). The covers do not require full transparency to be penetrated by radar beams. For example it is possible to look through black plastic sheets. A small portion of the radar beam will be reflected back to the sensor from the cover. Through a special teach-in-algorithm the sensor learns the profile of the reflection. It subsequently measures objects behind the cover, as if the cover is none-existent.

The radar sensor is also available in a configuration, where it operates similar to a light barrier. Via a special teach-in-algorithm the sensor learns the reflector position. After teaching the sensor monitors the reflector position. If an object breaks the line of sight between the sensor and reflector, the sensor output switches. The advantage of this configuration is that it is unnecessary for the object to reflect a signal back to the sensor. Therefore even randomly-shaped objects or radar absorbing objects can be reliably detected.
