A radar echo is the reflection of the radar signal off objects in the environment, such as other vessels, land formations, or obstacles. The strength of the radar echo indicates the size and distance of the object, while the shape and clarity of the echo provide information about the object’s characteristics. Radar echoes are key to detecting and identifying objects in the surrounding area, and modern radar systems are equipped to filter out unwanted noise and clutter, ensuring that the most important echoes are detected and displayed for the operator.
