Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a split-type radar mast. Background Technology

[0002] In existing technical solutions, radar masts are integral units. On some ships, if obstructions near the radar mast are too high or too large, they can affect the transmission and reception of antenna signals on the radar mast.

[0003] When an integral radar mast is obstructed by an obstacle (such as a chimney), the signals of the X-band radar antenna, the satellite communication C-station antenna, and the VSAT antenna are blocked, causing the integral radar mast to fail to meet the specifications and performance requirements of these antennas.
