Technical Field
The utility model relates to a radar aided design technical field especially relates to a radar auxiliary system based on boats and ships automatic identification system.
Background
The Automatic Identification System (AIS) of the vessel is composed of shore-based (base station) facilities and shipborne equipment, and is a novel digital navigation aid System and equipment integrating network technology, modern communication technology, computer technology and electronic information display technology.
The Automatic Identification System (AIS) of the ship is developed by the enemy and my recognizer of the ship and airplane, and is matched with a Global Positioning System (GPS) to broadcast the ship position, ship speed, course rate and course and other ship dynamic static data combined with ship names, call signs, draught, dangerous goods and other ship static data to ships and shore stations in nearby water areas through Very High Frequency (VHF) channels, so that the adjacent ships and shore stations can timely master the dynamic and static information of all ships on nearby sea surfaces, and can immediately coordinate communication with each other, take necessary avoidance actions and greatly help the safety of the ships.
The high-frequency surface wave radar developed by Wuhan university radio wave propagation laboratory is a radar system for detecting ocean environment elements such as ocean surface wind, wave, flow field, low-speed moving target and the like, and the system adopts a linear frequency modulation pulse compression technology and a multi-channel receiving technology and obtains abundant ocean information by using an array signal processing technology. The accuracy of the relevant information detected by the radar is checked, and the relevant information recorded by the ship is compared with the information detected by the radar usually through matching of the ship with the target ship going out from the sea. This comparison is cost prohibitive and yields a small amount of information due to the large cost of the ship going to sea. The system is very suitable for auxiliary radar because the automatic ship identification system can obtain the flight path conveniently and accurately and has low cost.
The Digital Beam Forming (DBF) is to compensate the phase difference caused by the propagation path difference introduced by the sensors with different spatial positions in a digital mode, so that the signals of all paths are superposed in phase, the energy in the observation direction is received to the maximum, and the target signal detection in the specific direction is formed. The key to the implementation of the DBF processing technology is the amplitude and phase consistency among the channels and the stability of the channels themselves, and in practical applications, the errors among the channels are inevitable. Generally, the amplitude-phase error of a receiving channel is divided into two parts: one part is that the error of each receiving channel can change along with the change of environment, the fault of the assembly and the like, and the correction is needed when the computer is started every time; the other part is the channel error of each unit, which is mainly caused by the inconsistency of the antenna array. These errors, if not corrected, can severely degrade antenna pattern characteristics. The influence of the characteristic inconsistency among the channels on the array signal processing system is very large, so that the channel consistency is a precondition for the array signal processing.
