Marine radar interference can occur due to various factors such as nearby electronic devices, radar cross-talk, or environmental conditions. Interference can cause reduced image clarity, making it harder to detect targets or obstacles. Common sources of interference include nearby radios, sonar equipment, and other radar systems. To minimize interference, boaters should ensure that their radar systems are properly shielded and that electronic devices are correctly installed and calibrated. If interference continues, adjusting the radar settings or seeking professional help can help resolve the issue and improve radar performance.
