Ship automatic identification system (AIS) is formed by the radio recognition equipment development of naval vessel aircraft, cooperate GPS (GPS) that boats and ships such as accommodation, ship's speed, the rate of changing course and course are dynamically broadcasted near waters boats and ships and base station by very high frequency(VHF) (VHF) channel in conjunction with boats and ships static datas such as name of vessel, catchword, drinking water and dangerous cargos, make contiguous boats and ships and base station can in time grasp near the sound attitude information of all boats and ships of sea, be able to conversation coordination mutually at once, take necessity to dodge action, safety of ship is had very great help.
The high frequency surface wave radar of Wuhan University's wave propagation laboratory development is a radar system of surveying Marine Environmental Elements such as ocean surface wind, wave, flow field and low speed moving target, system has adopted chirp compress technique and hyperchannel reception technique, use array signal process technique, obtain abundant marine information.For radar detection to the accuracy of relevant information test, often by the cooperation of going to sea of target ship, utilize ship note relevant information and radar detection to information compare.Because the cost that ship goes to sea is huge, this way of contrast cost is too high, and the quantity of information that obtains is less.Since ship automatic identification system obtain flight path comparatively convenient, accurately to reach cost low, native system is well suited for backup radar.
Digital beam forms (DBF) and compensates with the phase differential that the propagation path difference that the digital form sensor that the locus is different is introduced causes, thereby realize that signal is with superimposed between each road signal, make the maximum reception of observed ray energy, form echo signal detection on the specific direction.The key that the DBF treatment technology is realized is the stability of each interchannel amplitude, phase equalization and passage itself, and in the application of reality, interchannel error is unavoidable.Usually the receiving cable amplitude phase error is divided into the two large divisions: a part is that the error of each receiving cable can change with the variation of environment, the fault of assembly etc., and each start all needs to proofread and correct; Another part is the channel error of each unit, and mainly the inconsistency by aerial array causes.Will the havoc antenna pattern characteristic if do not proofread and correct these errors.The inconsistency of characteristic is very big for the influence of array signal processing system between the passage, and passage consistency is the prerequisite of Array Signal Processing thus.
The utility model content
The purpose of this utility model provides a kind of radar auxiliary system based on ship automatic identification system, to utilize radar auxiliary system to form the ship ship trajectory, the data measured with radar compare, add and merge, with the accuracy of check detections of radar target and improve targetpath.
For achieving the above object, the utility model adopts following technical scheme:
A kind of radar auxiliary system based on ship automatic identification system comprises:
