Marine navigation radar is known as the “eyes” of ship navigation. It is not only a core navigation equipment mandated by the International Maritime Organization (IMO), but also key equipment for safe navigation and maritime management. Its core application scenarios are as follows:
In ports, waterways and island-dense areas, the radar detects shorelines, buoys, navigation aids and other vessels in real time, assisting the ship in maintaining accurate course and safe distance to avoid grounding, stranding or collisions.
Navigation In Bad Weather & Low Visibility
In fog, rainstorms, nighttime and other low-visibility conditions, radar works unaffected by weather and provides all-weather environmental perception to ensure navigation safety.
Collision Avoidance Decision Support: With ARPA (Automatic Radar Plotting Aid) function, it automatically tracks position, course and speed of target ships, calculates collision risks and gives early warning, helping the operator take timely evasive actions.
2. Port & Terminal Operations
Berthing & Unberthing Assistance
When entering or leaving ports and berthing, radar monitors the positions of berths, breakwaters and other operating vessels, helping the operator control speed and course accurately to avoid collisions.
Anchorage Management
In dense anchorages, radar monitors the movement of nearby ships to prevent dragging anchor and collisions, ensuring anchoring safety.
Shore-Based Monitoring & Dispatch: Shore-based radar provides full-domain monitoring of ships in ports, waterways and anchorages, supplying real-time traffic data to VTS centers for vessel dispatch, channel control and emergency response.
Vessel Traffic Control
In busy waterways such as straits and canals, radar monitors traffic volume, identifies violations, maintains navigation order and improves channel efficiency.
4. Special Vessels & Operating Scenarios
Fishing Vessels
Radar detects fish echoes and other ships in operating areas, assists safe fishing and avoids obstacles such as fishing nets and reefs.
Engineering / Special Vessels
Dredgers, crane ships, rescue ships and other special vessels use radar to monitor on-site environments, support positioning and obstacle avoidance to ensure construction and rescue safety.
Inland Vessels: In complex and dense inland waterways, radar helps detect surrounding targets and avoid shoals, bridges, buoys and other obstacles to improve safety.
5. Emergency & Security Support
Search and Rescue For Distressed Vessels:When ships are in distress or people fall overboard, radar assists in locating targets and provides key guidance for rescue operations.
Anti-Piracy & Security: In high-risk waters, radar detects small boats, speedboats and other suspicious targets in advance to support early security warning.
