Radar Sensor for Agricultural Automation

The opportunity to trial a cost-effective, single-sensor solution for agricultural automation to increase the efficiency and safety of your operations

The challenge

Manual operation of farming machinery can be expensive and productivity is often reduced in adverse conditions. The use of large machinery also poses safety risks to people along with the possibility of costly collisions and the associated downtime that incurs. Typical automation sensors that are used to help increase productivity and safety, are often affected by bad weather, light conditions and loss of visibility due to the agriculture environment, such as heavy dust, leading to significant downtime.

Navtech Radar’s sensors are a reliable addition to agricultural machinery for automation. Our sensors are easily integrated with existing equipment, providing reliable data for navigation, anti-collision and process monitoring, in all weather and environmental conditions. We are currently developing a miniaturised version of our market-proven CIR sensor, which has a faster update rate, smaller form factor and will be cost-effective for agricultural applications. The smaller prototype sensor is called the CAS sensor.

How will it work?

A single sensor, mounted on each vehicle, can be easily integrated into any automation control system using our Robot Operating System (ROS) implementation. Working beyond the limits of a person’s capability, our sensors can see when humans can’t, adding an extra layer of safety to challenging environments. They are capable of operation 24/7, in all-weather and lighting conditions, from bright sunlight to complete darkness.

The sensor provides a rich data output that can be used by your system to deliver operation monitoring, navigation and anti-collision capabilities, specifically localisation, perception, anti-collision and obstacle detection. 

What do these capabilities all mean for the automation of agricultural machinery? Localisation answers the question for autonomous vehicles: Where am I? Perception answers the question: What is around me? Anti-Collision tells your vehicle: What is around me and if I don't want to hit it, what's the action I take? Whilst, Obstacle Detection tells your vehicle there is a person or vehicle close to it. 

These are all capabilities we have deployed for industrial automation in environments such as mines and ports, using our CIR sensor, which will now become cost-effective for agricultural application with the smaller CAS sensor.

Expected technical performance

What performance can you expect from this new solution? Our world-leading sensors work in all environments, all the time delivering reliable performance in rain, fog, dust and dirt, when other sensors fail. 

The high-resolution, 360°, long-range radar builds a data-rich picture of its surroundings, whatever the conditions.  Capable of operating in all light conditions including complete darkness, it can be easily integrated into any system with our ROS code examples. With unrivalled availability, our sensors work in all-weather so you can operate your site 24/7 safely and efficiently. Working beyond the limits of a person’s capability, they can see when humans can’t, adding an extra layer of safety to challenging environments.

Technical specifications

Trials to date

CEREMA Testing, June 2021

In order to test the performance of the CAS in adverse weather conditions, the prototype radar was sent to a specialised facility based in France. The Cerema PAVIN platform provides a controlled environment, ensuring measured and repeatable disruptive weather events such as rain and fog so performance can be monitored. 

In our testing, radar targets and a test object (a car exhaust) were placed at varying distances from the CAS sensor, moving gradually out to the full test range of the chamber.

The chamber was filled with fog with a meteorological optical range of less than 10 metres and the performance of the radar was not impacted at all, successfully detecting both the exhaust and radar targets throughout the fog testing. These tests were conducted as part of our involvement with the Award project, which aims to bring major innovations to the transport industry, fleet operators and the entire logistics sector.
