Advanced Application of JWrada® 80GHz High-Frequency Radar Level Meter in Vessel Docking Distance Monitoring

As global maritime trade becomes increasingly busy, port operational efficiency and vessel navigation safety have become the focal points of the industry. In the critical link of ship berthing, accurately monitoring the distance between the vessel and the pier to assist crews in real-time attitude adjustment is not only vital for smooth loading and unloading but also central to preventing pier collisions and safeguarding assets.

As a leader in the field of level measurement, Jiwei Automation has introduced the JWrada® 80GHz High-Frequency Radar Level Meter. With its superior measurement precision and unique cloud-based remote debugging software system, it provides a high-efficiency and reliable new solution for intelligent port berthing.

1. Challenges in Vessel Berthing Distance Monitoring

The ship berthing process is influenced by various dynamic factors, and traditional measurement methods often struggle to meet the requirements of modern smart ports:

• Complex Environmental Interference: Ports are often accompanied by wave fluctuations, tidal changes, and harsh weather such as rain, snow, or fog, demanding extremely high stability of measurement signals.
• Measurement Dead Zone Restrictions: During close-range docking, low-frequency radars often have large dead zones, failing to provide reference data at critical terminal distances.
• Difficulties in Debugging: Port environments are open, and equipment is often installed at high elevations or on the edge of the pier. On-site debugging by engineers is costly and poses safety risks.
• Poor Adaptability to Working Conditions: Different vessel types and pier structures have varying reflection characteristics; general algorithms often fail to achieve ideal measurement accuracy.

2. JWrada® 80GHz Radar: The Hardcore Power of Precision Perception

Designed specifically for the needs of berthing monitoring, the JWrada® series radar level meters demonstrate significant technical advantages:

80GHz FMCW Technology for High Precision

JWrada® utilizes 80GHz Frequency Modulated Continuous Wave (FMCW) technology. Compared to traditional 26GHz radar, it features a smaller beam angle (as narrow as 3°) and more concentrated energy. In ship berthing applications, this means it can effectively avoid obstacles like pier fenders and bollards, accurately locking onto the side of the hull to achieve millimeter-level distance measurement.

Zero Dead Zone

Due to the characteristics of high-frequency signals, the JWrada® dead zone is zero. In the final meters or even centimeters of docking, the radar continues to output stable distance data, providing critical reference for the crew to adjust berthing speed and angles.

Strong Penetration and Anti-interference Capability

The device is equipped with excellent signal processing algorithms capable of filtering out false echoes caused by wave fluctuations. Even in heavy storms or thick fog, it can penetrate atmospheric interference to obtain true hull reflection signals.

3. Core Competitiveness: Self-developed “Cloud-based Smart Brain” Software

If the hardware is the “eyes” of the radar, then the self-developed software system is the “brain” that puts JWrada® ahead of domestic competitors. While most domestic manufacturers remain at the stage of hardware imitation, Jiwei has achieved a generational leap at the software level.

Unique Cloud Server Remote Debugging Mechanism

This is the most competitive feature of JWrada®. Through built-in or external communication modules, the radar connects to the Jiwei Cloud Platform.

• One-on-One Remote Collaboration: Senior engineers do not need to visit the port in person. They can collaborate with on-site personnel synchronously via the cloud.
• Real-time Viewing of Echo and EFT Curves: Engineers can remotely retrieve real-time echo curves. EFT (Interference Suppression Curve) analysis is a specialty of Jiwei, allowing for accurate modeling and shielding of interference echoes to ensure only the ship hull signal is identified in complex pier structures.

Customized Parameter Optimization and Algorithm Adjustment

Every port berth has unique conditions. JWrada® software supports dynamic algorithm adjustments based on on-site echo characteristics. For the dynamic movement during berthing, engineers can modify signal damping and update tracking gate algorithms to ensure data output is both smooth and responsive.

Comprehensive Device Health Management

• Online Software Updates: As algorithms iterate, users can remotely upgrade firmware to maintain peak performance.
• Parameter Settings and Fault Code Access: On-site or remote engineers can quickly troubleshoot anomalies. The fault code system accurately determines whether an issue is signal blockage, power fluctuation, or sensor status abnormality, significantly reducing maintenance downtime.

4. Integration and Application Scenarios in Berthing Control Systems

JWrada® radar level meters typically serve as the sensing layer integrated into Docking Aid Systems (DAS):

• Multi-point Linked Monitoring: Installing multiple JWrada® radars at the pier front to measure distances at the bow, midship, and stern to calculate the vessel’s yaw angle and approach speed.
• Crew Auxiliary Display: Data is transmitted via wireless or wired means to the control center and displayed simultaneously on large pier screens or crew handheld terminals.
• Safety Warning: When the berthing speed is too fast or the distance is below the safety threshold, the system automatically triggers an alarm to remind the crew to take emergency measures.

5. Why Choose Jiwei as a National Replacement?

Under the “Nationalized Replacement” strategy, Jiwei has become a preferred alternative to top German brands like VEGA.

• Source Manufacturer Supply: Jiwei has a complete production line and quality control system, ensuring every JWrada® meets industrial standards.
• Authoritative Certifications: Jiwei radar and level switch products hold authentic SIL2/3 Safety Integrity Level certifications, which are crucial in the safety-driven port and petrochemical industries.
• Full Industry Chain Service: From PetroChina and Sinopec to Tesla and Coca-Cola, Jiwei has proven its stability in high-end fields. In ship berthing, we provide full life-cycle services from model selection to cloud maintenance.

6. Conclusion

The construction of smart ports is inseparable from precise perception. The JWrada® 80GHz radar level meter not only reaches the top tier of physical measurement but also solves the pain points of difficult on-site debugging through cloud-based remote algorithms.

Choosing Jiwei means choosing more than a high-precision sensor; it is choosing a smart berthing solution that evolves with working conditions and is guarded in real-time by professional engineers.
