Which RADAR frequency band is typically used for maritime navigation?

The S-band is typically used for maritime navigation due to its effective balance of range and resolution, making it suitable for the detection of large vessels and navigation aids. Operating in the frequency range of approximately 2 to 4 GHz, the S-band provides adequate radar wave propagation, allowing for longer detection ranges while still offering sufficient detail for navigation tasks. This is particularly important in maritime environments where vessels must navigate safely in congested waters and in varying weather conditions.

The S-band’s characteristics make it particularly advantageous for long-range tracking and surveillance applications at sea. It is less affected by rain and other atmospheric conditions compared to higher frequency bands, which helps ensure reliable operation in diverse weather scenarios commonly encountered in maritime settings.

In maritime navigation, the radar systems utilizing S-band can help marine operators avoid collisions, monitor surrounding traffic, and assist with anchoring and docking maneuvers, which are critical for safe vessel operation.
