You’ll learn how radar works, including the components, signal structure, and how to safely operate the system. The course covers interpreting radar screens, optimizing settings for different conditions, and using radar for navigation and collision avoidance. You’ll practice piloting using radar, tracking targets, anchoring, and navigating in challenging visibility. With hands-on experience in radar operation and interpretation, ASA 120 equips you to navigate safely and efficiently, even in the most demanding environments.  \n| PREREQUISITES:\u003Cbr>• ASA 105-Coastal Navigation\u003Cbr>And the ability to demonstrate competencies in all knowledge and skills elements of that Standard. | STUDY MATERIALS:\u003Cbr>•  Radar for Mariners by David Burch (McGraw Hill, 2013)\u003Cbr>• USCG Navigation Rules & Regulations Handbook |\n| --- | --- |\n\nASA 120-RADAR ENDORSEMENT STANDARDS  \nKNOWLEDGE:  \n1.
