What are low-speed radar sensors?

Core function and technology

You use low-speed radar sensors to measure the movement of your farm machinery with high accuracy. These sensors help you track how fast your equipment moves across the ground, even at very low speeds. You can install them on tractors, harvesters, or other vehicles. The main technology behind these sensors is 24 GHz millimeter-wave (mmWave) radar. This advanced radar uses Frequency Modulated Continuous Wave (FMCW) techniques. The sensor sends out a frequency-modulated signal and listens for the reflection from the ground. By comparing the outgoing and incoming signals, the sensor calculates both distance and speed. This method works well in dust, mud, and changing weather.

You can connect these sensors to your equipment using CAN bus, RS485 or pulse output. This makes them compatible with both older and newer machines. The rugged housing protects the sensor from chemicals, impacts, and harsh weather. You do not need to worry about damage during tough fieldwork.

Ground speed measurement

You rely on true ground speed measurement to get the best results from your farm equipment. Low-speed radar sensors use FMCW radar to detect even small movements. This gives you a precise reading of how fast your machine moves over the soil. Unlike estimated speed methods, this technology does not depend on wheel slip or GPS errors.

• You get reliable yield estimates from your grain yield monitors.
• You avoid errors in yield data that happen when ground speed falls outside the calibrated range.
• You reduce the risk of yield estimate mistakes, which can be as high as 23% if you use less accurate speed methods.

Accurate ground speed helps you apply seeds, fertilizer, and chemicals at the right rate. You improve your harvest quality and reduce waste. With low-speed radar sensors, you make better decisions and get more value from every pass through the field.

Improved efficiency

You want to get more done in less time. Low-speed radar sensors make your work more efficient by guiding your machinery with precision. These sensors measure your speed and position accurately, so you apply seeds, fertilizer, and chemicals at the right rate. You avoid overlap and missed spots, which saves you money and resources.

You also experience less fatigue. The radar system can automate steering and row turns, letting you focus on other important tasks. You spend less time correcting mistakes or redoing work. Your equipment covers more acres in a day, and you make fewer passes over the same ground.

Increased productivity

You need tools that help you get the most from every acre. Low-speed radar sensors give you the accuracy and control you need for high productivity. The sensors use high-frequency radar to measure distance and speed with great precision. You can mount them at different heights and angles to fit your equipment and field needs.

• You achieve accurate ground speed readings, even at very low speeds.
• You reduce errors in planting, spraying, and harvesting.
• You improve your yield by applying inputs exactly where needed.

Many modern radar ground speed sensors, such as Zlyradar’s TGSS radar sensor , offer Less than ±1km/h Measurement Error. They work across a wide range of speeds, from0.36km/h to 50km/h. This flexibility means you can use them for many types of fieldwork, from slow planting to fast spraying.

You also support automation. As more farms adopt autonomous tractors and smart implements, these sensors become essential. They provide the data needed for machines to operate safely and efficiently without constant human input.

With these advantages, you can focus on growing your business instead of worrying about equipment errors or wasted resources.

Applications of low-speed radar sensors

Tractors and harvesters

You can install True Ground Speed Sensors (TGSS radar sensor) on a wide range of farm machinery. Tractors and harvesters benefit the most from this technology. When you mount a ground speed radar sensor on your tractor, you get accurate speed readings even on muddy or uneven fields. This helps you control planting, spraying, and harvesting with greater precision. Many farmers use these sensors to replace unreliable wheel speed sensors. You avoid errors caused by wheel slip or soft soil. You also improve the accuracy of your yield monitors and application rates.

Tip: Choose a sensor that supports both CAN and pulse output. This ensures compatibility with older tractors and the latest smart harvesters.

 

Autonomous systems integration

You can use low-speed radar sensors to support autonomous and semi-autonomous farm equipment. These sensors provide real-time ground speed and obstacle detection data. Your autonomous tractor or sprayer can adjust its speed and path based on this information. This leads to safer operation and better field coverage. Many smart farming systems rely on radar-based ground speed sensors for precise control. You can integrate these sensors with GPS and other guidance systems for even more reliable performance.

Real-world use cases

Farmers around the world trust radar ground speed sensors for tough jobs. For example, you might use a zlyradar sensor on a self-propelled sprayer. The sensor measures true ground speed, so you apply chemicals at the correct rate. In another case, you could install a rugged radar sensor on a combine harvester. The sensor helps you maintain steady speed through thick crops and uneven terrain. Many users report fewer missed spots and less overlap during planting and spraying.

You can depend on these sensors for accurate crop penetration and ground detection. This technology works in dust, rain, and heavy residue, giving you confidence in every pass.

Maintenance and reliability

You want technology that works reliably in harsh field conditions. Most low-speed radar sensors feature rugged construction, which means less frequent maintenance and a longer service life. You can keep your sensors in top shape by following a few simple steps:

Perform visual inspections before each season.
Check electrical connections and mounting hardware.
Calibrate the sensor as recommended by the manufacturer.

FAQ

What is a ground speed radar sensor, and how does it work?

A ground speed radar sensor uses millimeter-wave radar to measure your machine’s movement over the soil. It sends signals to the ground and calculates speed by analyzing the reflected waves. You get accurate readings, even in mud, dust, or low visibility.

Can I install a precision speed sensor on older tractors?

Yes, you can. Most agricultural radar sensors support CAN bus, RS485 and pulse output. This means you can connect them to both legacy and modern equipment. You do not need to upgrade your entire fleet to benefit from this technology.
