Marine radar for oceanographic observation having HH-polarization antenna and VV-polarization antenna

摘要

PURPOSE: A sea observing radar having an HH polarized wave antenna and a VV polarized wave antenna is provided to accurately distinguish maritime data and position data of obstacles and ships. CONSTITUTION: A sea observing radar comprises a antenna unit(110). The antenna unit transmits and receives electromagnetic waves of a specified region. The antenna unit comprises HH polarized wave antenna(111) and a VV polarized wave antenna(112). The HH polarized antenna observes location of obstacles, ships, and coast by using horizontally polarized waves. The VV polarized wave antenna observes maritime data including sea surface information or flowing information of seawater by using vertically polarized waves.
