Navigation mark with annular phased-array radar

Abstract

The invention relates to a navigation mark with an annular phased-array radar, comprising a navigation-mark ship, wherein a navigation-mark lamp and a navigation-mark tower are disposed on the navigation-mark ship, and the navigation-mark lamp is connected with the navigation-mark ship via the navigation-mark tower. The navigation mark with an annular phased-array radar further comprises a phased-array radar with a plurality of phased-array antennas, wherein the phased-array antennas are disposed on the navigation-mark tower around the navigation-mark tower to form an annular phased-array antenna layer. The navigation mark disclosed by the invention has the following advantages that: 1, a radar navigation mark low in energy consumption and high in reliability is provided, and via the radar navigation mark, ships know the situations of ships and channels around water body, so that the ships smoothly finish navigation, and safety is ensured; 2, the phased-array antenna layer is fixed below the navigation-mark lamp, and by means of static fixation, the rotation wear of mechanical device and circuit is reduced, the reliability of radar is enhanced, and the cost of radar is decreased; and 3, metal discs are installed on the upper surface and the lower surface of the phased-array antenna layer, and used for preventing electromagnetic wave from being absorbed by water body, so that the gains of phased-array antennas are increased.

Description

technical field [0001] The invention relates to a navigation mark, in particular to a navigation mark with an annular phased array radar. Background technique [0002] Aids to navigation are set in or near navigable waters to mark the location of waterways, anchorages, shoals and other obstacles to navigation, to indicate water depth and style, and to direct traffic in narrow waterways. Radar is installed on the navigation mark now, so that the ship can accurately know the situation around itself. At present, the rotating scanning radar is generally used to search the surrounding ships. The mechanical rotating drive mechanism consumes a lot of power, and if the rotating radar is in the harsh environment of wind, waves and shaking for a long time, the rotating mechanism is very easy to fail, resulting in damage to the radar scanning; Scanning radar is only a single positioning, and cannot scan the surrounding environment in all directions at the same time, so there are poten...
