Introduction
Marine radar is one of the most reliable tools for safe navigation, especially in restricted visibility. This article explains how officers use radar in real conditions.
How Radar Works (Simple Explanation)
Radar sends radio waves and receives echoes from objects to determine their position.
Practical Use in Navigation
1. Target Detection
- Identifies nearby ships
- Tracks movement
2. ARPA Function
- Automatically calculates CPA and TCPA
- Tracks multiple targets
Radar Plotting Simplified
- Manual plotting helps predict collision risk
- Still important despite automation
Restricted Visibility Scenario
- Use radar continuously
- Reduce speed
- Sound fog signals
Common Mistakes
- Over-reliance on ARPA
- Poor tuning of radar
- Ignoring small targets
FAQs
Q1: Can radar detect all objects?
No, small boats may not appear clearly.
Q2: Is radar better than AIS?
Both are complementary tools.
Conclusion
Radar remains the backbone of navigation safety even in modern ships.
