Which of the following is NOT a reason for using RADAR in navigation?

Using RADAR in navigation serves several critical functions, and determining wind direction is not one of them. RADAR is primarily designed for detecting objects and measuring distances, which allows mariners to identify and track vessels, navigate around obstacles, and enhance situational awareness.

Identifying buoys is a key aspect of RADAR use, as it helps in recognizing navigational aids in the water. Likewise, referencing maps is crucial since RADAR systems can overlay real-time data with electronic charts, enhancing navigational accuracy. Monitoring other vessels is an essential RADAR function, enabling the detection and tracking of nearby ships to prevent collisions and ensure safe navigation.

Wind direction, however, is typically assessed through different means, such as anemometers or visual observations, rather than through RADAR technology. RADAR does not provide direct information about wind patterns, making it an unsuitable tool for that specific need.
