<p>The present invention relates to a vessel mast having improved a radar function. The vessel mast comprises a mast ship body having various radars and antennas installed therein; yard arms formed to be perpendicularly extended from both sides of the upper end of the mast and having a radar and a sensor. The mast ship body is formed to be a trapezoidal prism getting smaller in size toward the upper end from the lower end and to be a pyramid shape in a plane having the front side smaller in width than the rear side. Each yard arm is configured to be a trapezoidal prism getting smaller in size toward the outer side. The mast ship body of the mast and the yard arms are formed to be a trapezoidal prism. Therefore, weight reduction and a design for low center of gravity can be possible. Also, a knuckle point does not exist. Therefore, the mast having a stable structure can be provided. Moreover, the RCS signal of radar can be reduced and the interference of a transmission signal does not exist.</p> |
