Description
Technical Field
The invention belongs to the technical field of phased array antennas, and particularly relates to a method for determining an installation inclination angle of a carrier plane phased array antenna under the condition that a ship is in a motion attitude.
Background
The planar phased array antenna is an array antenna in which antenna units are distributed on a plane, and antenna beams can be scanned in a phased manner in both azimuth and elevation directions. Phased array antennas rely mainly on phase changes to effect movement or scanning of the antenna beam pointing in space, and phase shifters are arranged at the rear end of each antenna element to change the phase relationship of signals between the elements, and amplitude changes of the signals are realized through a power distribution/addition network or an attenuator. For a ship-borne platform, a phased array antenna array surface is generally mounted in a conformal manner with a ship mast surface and designed integrally due to the requirement of radio frequency integration. To achieve scan coverage in the azimuth 360 range, typically more than 3 antenna planes are required. Meanwhile, in order to enable the phased array antenna to have better airspace coverage characteristics, each antenna array surface has a certain installation inclination angle. In general, the electrical performance of a phased array antenna deteriorates with increasing scan angle, and the larger the scan angle at which the antenna main beam deviates from the normal to the array plane, the larger the gain drop. Therefore, it is important to reduce the maximum scan angle of the phased array antenna as much as possible while satisfying the coverage area. To reduce the scan gain drop, minimizing the maximum scan angle is one of the design methods of the array surface mounting tilt angle. When the installation platform of the phased array antenna is under the condition of a motion gesture, such as course change, pitching and rolling of a ship in the sailing process, different installation dip angles can cause the change of a maximum scanning angle for a coverage airspace determined by the phased array antenna.
At present, reports of various documents focus on the study of the installation inclination angle of a phased array antenna under the condition of a static platform. The calculation of the optimum face mounting tilt under hemispherical airspace coverage conditions is reported in the literature "Choosing the Number of Faces of a Phased-Array Antenna for Hemisphere Scan Coverage" (IEEE Transactions on antennas and propagation, vol. Ap-13, pp. 878-882) published by george. H et al in 1965. At this time, the maximum scan angle of each antenna array plane is equal, and the value is also minimum. However, this document only analyzes a stationary platform in a hemispherical coverage condition. The method of designing the best tilt angle of the phased array antenna for any coverage airspace is reported in the literature (determination of the best array tilt angle and the maximum cell pitch of a planar phased array antenna) (Shao Jiangda, modern radars, 1997, 19 (1): 49-53), but the literature only analyzes that the phased array antenna is in a static platform condition.
When the installation platform of the phased array antenna is under the condition of motion gesture, such as course change and longitudinal and transverse swinging of a ship in the sailing process, the beam direction of the phased array antenna needs to be corrected by adjusting the scanning angle. The electronic stabilization platform compensates beam pointing deviation generated by ship attitude change by calculating the phased array antenna beam pointing angle. The prior patents and articles discuss methods of compensating an electronic stability platform. For example, the literature (Cao Zhengcai. General stable mode coordinate transformation of ship-borne radars [ J ]. Radar and countermeasure, 2010, 30 (1): 47-52.) and (Qiufei, wang Cong. Coordinate system transformation method of ship-borne radar reconnaissance system. Ship electronic countermeasure, 2017, 40 (5): 34-39) deduce a ship electronic stability compensation formula and azimuth angle and pitch angle of antenna beam. The 2014 China patent (application number: 201410704439.2) discloses a beam pointing correction method for a ship longitudinal and transverse integrated vector coordinate transformation antenna. None of the prior documents and patents analyze the installation inclination angle of the phased array antenna array surface under the condition of motion gesture.
