What does 'Sea' do in terms of radar performance?

In the context of radar performance, 'Sea' refers to the environment that can affect the radar signals as they interact with the water surface. Suppressing sea clutter is essential for improving radar performance, particularly in maritime navigation.

Sea clutter consists of unwanted echoes that arise from waves, swells, and other surface phenomena, which can obscure or mask the radar return signals from other objects, such as vessels or navigation aids. By effectively suppressing this clutter, the radar system can enhance the clarity and accuracy of the readings, allowing for better detection of objects of interest even in rough sea conditions.

This suppression allows navigators to make more informed decisions based on the radar data, improving safety and situational awareness at sea. Understanding how sea clutter affects radar is crucial for effective navigation and avoiding potential hazards.
