The invention relates to the technical field of satellite-ground laser communication, and discloses a banyan-shaped network communication method and system based on multi-beam multipath transmission and space diversity synthesis aperture reception. The method comprises the following steps: dividing a light beam into a plurality of beams at a satellite-based terminal through beam forming to point to a plurality of ground stations; multiple ground stations receive data in parallel and then gather the data to a data center for time-space synchronization; and the data center adopts a multi-branch neural network to intelligently fuse the synchronized data so as to reconstruct a signal. According to the invention, by constructing the satellite-to-ground collaborative architecture, signal interruption and data loss caused by atmospheric turbulence are effectively suppressed, the limitation of high-error-code communication is broken through, and remote, high-speed and high-reliability satellite-to-ground communication is realized.

The invention relates to the technical field of landscape bridges, and discloses an arch-shaped cable-stayed combined beam column structure and a construction method of the arch-shaped cable-stayed combined beam column structure. The middle of the main beam is connected with the top of the pier column; a main arch ring; the number of the arch feet is two, the two arch feet are arranged at the two ends of the main arch ring respectively, and the arch feet are connected with the two ends of the main beam respectively; a first web member; when loads such as a vehicle are generated on the top face of the main beam, horizontal thrust independently balanced by the axial tension of the main beam is offset by the bending moment and the shearing force of the pier column; the main arch ring connected with the web member exerts upward supporting force on the main beam, large hogging moment is prevented from being generated at the joint of the main beam and the pier column in the T-shaped structure, the main beam, the pier column, the main arch ring and the web member form a beautiful shape similar to a big banyan tree on the vertical face, and the comprehensive performance of large span, low height, high adaptability and unique landscape effect is achieved.

The invention belongs to the technical field of navigation communication antennas, and particularly discloses a miniaturized multi-band composite antenna, which comprises a ring focus reflector antenna, a banyan array antenna and a frequency selective surface, the ring focus reflector antenna comprises a main reflector, an auxiliary reflector and a multi-ripple feed source, the concave surface of the main reflector is opposite to the convex surface of the auxiliary reflector, and the multi-ripple feed source is arranged at the axis of the main reflector. According to the miniaturized multi-band composite antenna and the assembly thereof provided by the invention, multi-band efficient radiation is realized in a limited space through cooperative layout of the ring focus reflector antenna, the special-shaped array antenna and the frequency selective surface in combination with optimal design of the multi-ripple feed source and the banyan antenna group, and meanwhile, inter-band interference is suppressed by using the frequency selective surface, so that the antenna efficiency is improved. The antenna has the advantages of compact structure, excellent multi-band cooperative work performance and strong electromagnetic compatibility.
