Description
Technical field
The present invention relates to a kind of navigation mark, particularly relate to a kind of navigation mark with annular phased-array radar.
Background technology
Navigation mark be located at navigable water or its nearby, to indicate navigation channel, anchorage, danger, beach and the position of other dangers, represent the depth of water, landscape, the traffic of commander's narrow waters.Existing radar is loaded on navigation mark now, makes ship can accurately know the situation of oneself periphery.At present the general spin scanning radar that adopts is searched for around ship, and its mechanical rotary drive mechanism consumption of current is larger, and if the harsh environment that rotating radar is in stormy waves for a long time and rocks, rotating mechanism very easily lost efficacy, and caused radar scanning to be damaged; Moreover spin scanning radar is monomer location, can not carry out comprehensive scanning, therefore there is potential safety hazard to surrounding environment simultaneously.Therefore, we are high in the urgent need to a kind of low energy consumption, reliability, can to the radar marker carrying out comprehensive scanning around simultaneously, to ensure the safety of boat trip.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of low energy consumption, reliability is high, can to the radar marker carrying out comprehensive scanning around simultaneously, to ensure the safety of boat trip.
Have the navigation mark of annular phased-array radar, it includes beacon vessel, and beacon vessel is provided with beacon light and navigation mark tower, and beacon light is connected with beacon vessel by navigation mark tower; It also comprises the phased array radar with multiple phased array antenna, and described phased array antenna is arranged on navigation mark tower around navigation mark tower for one week, forms H-Horn APA system antenna stack.
By such scheme, the quantity of described phased array antenna is 24.
By such scheme, described phased array antenna layer is circular, and the top of phased array antenna layer and/or below are provided with circular metal dish, and phased array antenna layer and salver are coaxially arranged, and the diameter of salver is greater than the diameter of phased array antenna layer.
By such scheme, the emissive power that described phased array antenna layer points to navigation channel is greater than the emissive power pointing to bank base.
By such scheme, the wave cover 360 ° of the electromagnetic wave composition of the launch and accept unit synthesis of described phased array antenna layer, and the position of beam intersects is not less than main lobe center 3dB.
Phased array radar has quite intensive aerial array, and the area of conventional radar antenna surface can install thousands of phased array antenna, and any one antenna all can receive and dispatch radar wave, and namely adjacent several antennas have the function of a radar.During scanning, selected one of them block (several antenna element) or several block scan simple target or region, and therefore whole radar can scan many targets or region or follow the trail of simultaneously, has the function of multiple radar.A radar can scan for different directions simultaneously, and scan mode is electron steering but not mechanical rotation, therefore, is installed in by phased array radar on navigation mark, has very large value.
Waveform generator produces relevant medium-frequency pulse, through upconverting to working frequency range, being distributed into 24 tunnel pumping signals by 1:24 power divider, being supplied to 24 row submatrix T/R assemblies on azimuth plane.Beamsteering Unit is selected adjacent 8 row submatrixs and is controlled each submatrix phase shifter, realizes step wise electronic scanning.The phase control code of phase shifter is calculated according to each submatrix coupler phase information fed back and the phase weighting relation formed needed for azimuth beam by Beamsteering Unit.Pumping signal after phase weighting is amplified by the solid-state power amplifier module in each submatrix, then forms network, circulator to dipole element unit by transmitted beams, forms transmitted beams in space.
In order to prevent electromagnetic wave from being absorbed by water body, below phased array antenna layer and/or above a salver larger than phased array antenna layer is installed.Because electromagnetic wave ratio is easier to be absorbed by water body, by salver, the electromagnetic wave that antireflection part scans the water surface, improves the gain of H-Horn APA system antenna.
Beneficial effect of the present invention is: 1, provide a kind of low energy consumption and the high radar marker of reliability, allows ship grasp ship and navigation channel situation around water body, makes ship complete navigation smoothly, ensure that safety.2, under phased array antenna layer being fixed on beacon light, owing to adopting static fixing, decrease mechanical device and circuit rotation wearing and tearing, improve reliability of radar, reduce the cost of radar.3, at the upper and lower surface dress salver of phased array antenna layer, prevent electromagnetic wave from being absorbed by water body, improve the gain of phased array antenna.4, can cut not needing the unit of scanning area, reducing the consumption of current of scanning.

Detailed description of the invention
Embodiments of the invention are further illustrated below in conjunction with accompanying drawing.
See Fig. 3 and Fig. 5, a kind of navigation mark 6 with annular phased-array radar, includes beacon vessel 7, beacon vessel 7 is provided with successively navigation mark tower, phased array antenna layer 2 and beacon light 5; Described phased array antenna layer 2 is made up of 24 phased array antenna 4, and 24 phased array antenna 4 are arranged on navigation mark tower around navigation mark tower for one week, are namely installed in the below of beacon light 5; The wave cover 360 ° of the electromagnetic wave composition of the launch and accept unit synthesis of described phased array antenna layer, and the position of beam intersects is not less than main lobe center 3dB.
In order to avoid the unnecessary wasting of resources, the emissive power that described phased array antenna layer 2 points to navigation channel refers to 2 times of the emissive power of onshore base to 10 times.Each transmitting terminal power that phased array antenna layer 2 described in the present embodiment points to navigation channel is 2-10w, and points to each transmitting terminal power 1w of bank base.
In order to allow the ship of surrounding understand the peripheral information of beacon light 5, by scanning collection to information carry out information fusion, generate geography information around and the peripherad boats and ships of ship information are issued.
See Fig. 2 and Fig. 6, described phased array antenna layer 2 is circular, absorbed by water body to prevent electromagnetic wave, above phased array antenna layer 2 and/or below be provided with circular metal dish 1,3, phased array antenna layer 2 and salver 1,3 are coaxially arranged, the diameter of salver 1,3 is greater than the diameter of phased array antenna layer 2, and general salver diameter is 1.2 to 1.5 times of phased array antenna layer diameter.In the present embodiment, salver diameter is 0.6m, and phased array antenna layer diameter is more smaller than salver, is generally 0.5m.Because electromagnetic wave ratio is easier to be absorbed by water body, by salver 1,3, the electromagnetic wave that antireflection part scans the water surface, improves the gain of loop antenna.
In order to reduce the consumption of current of scanning, some can not needed the unit of scanning area cut, by the n of scanning angle phased array antenna transmitter/receiver unit partial removal (24>n).
Track analysis can also be carried out to the boats and ships of Scan orientation on this basis, if there is driftage, wireless communication can be adopted to report to the police, inform shipowner and supervisory management zone.By hindering boat building and navigation channel information storage to carry out flight path information convergence analysis to the ship of Scan orientation, if boats and ships are close to danger, AIS wireless communication can be adopted to report to the police.
In order to improve the water-tight corrosion-proof of perimeter array radar, all unit are all sealed in organic material.
In order to improve the positioning precision of perimeter array radar, the mode of two perimeter array radar co-located can be adopted, providing a high accuracy data by the integration of two perimeter array radar locating information.
