A radar sensor detects the train within the tunnel.
In our ongoing series on vehicle detection technologies, we’ve explored various methods and their applications. Radar sensors have proven to be a reliable choice for detecting vehicles in different environments, especially when it comes to asset management, safety, and traffic control. This article will guide you on when and how to use radar sensors for vehicle detection, along with their key benefits.
Radar sensors utilize continuous frequency-modulated wave (FMCW) technology to detect both moving and stationary objects, such as cars, trains, trucks, and cargo, even in extreme weather conditions. Their ability to function reliably in harsh environments makes them an excellent choice for outdoor and industrial settings.
What is a radar sensor?
Radar sensors use FMCW technology to detect objects at a distance. They are capable of identifying vehicles even in challenging conditions like rain, fog, or dust, which can interfere with other types of sensors.
Advantages of radar sensors for vehicle detection
1. Remote Detection
Radar sensors are ideal for long-range applications. They can be set up to detect objects within a specific range while ignoring those beyond it, improving accuracy and reducing false positives.
2. Weather Resilience
Unlike photoelectric or ultrasonic sensors, radar sensors are not affected by weather conditions such as wind, rain, fog, or temperature changes. This makes them highly suitable for outdoor use, especially in areas where environmental factors can impact performance.
3. Flexible Installation
Radar sensors offer greater flexibility in installation compared to other technologies. They don’t need to be mounted directly on tracks, making them easier to install and maintain. This also reduces the risk of damage from high-impact forces, especially in environments like tunnels or loading docks.
The radar sensor detects large trucks at the loading dock.
Important Note
While radar sensors are effective for detecting large objects, they may struggle with small targets or closely spaced vehicles. Therefore, they are commonly used for detecting trains or large trucks, which are predictable and easier to identify.
