Embodiment Construction
[0042] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0043] In order to make the purpose, technical solution and advantages of the present invention clearer, specific embodiments will be described below in conjunction with the accompanying drawings.
[0044] As described in the background art, existing antennas can only rotate within a limited area, and are mainly used to align with a fixed station, such as aligning a mobile antenna on the ground wi...

The invention provides an antenna based on scatter communication and a communication system. The antenna comprises an antenna feeder subsystem, a structure subsystem and a servo control subsystem. The antenna feed subsystem comprises an antenna reflecting surface and a feed source; the structure subsystem comprises an azimuth waveguide joint, a pitching waveguide joint and a polarized waveguide joint which are connected in sequence, and the polarized waveguide joint is connected with the antenna feeder subsystem through a circular torque waveguide; the servo control subsystem comprises a servo main control module, an azimuth motor, a pitching motor and a polarization motor; and the servo master control module is used for controlling the azimuth motor, the pitching motor and the polarization motor to respectively drive the azimuth waveguide joint, the pitching waveguide joint and the polarization waveguide joint to perform conical scanning in the process of rotating to the target angle after receiving the target angle, so as to determine the angle with the strongest signal, and the azimuth waveguide joint, the pitching waveguide joint and the polarized waveguide joint are driven to drive the antenna feeder subsystem to rotate to an angle with the strongest signal. According to the invention, communication-in-motion follow-up tracking can be realized.
Description
technical field [0001] The invention relates to the technical field of scattering communication, in particular to an antenna and a communication system based on scattering communication. Background technique [0002] Troposcatter communication is communication using troposcatter channels. It has the advantages of stable and reliable channel resources, long-term existence, no need to pay, and strong anti-jamming, anti-interception, and anti-detection capabilities. It is widely used. [0003] At present, conventional scatter antennas are based on fixed station alignment, that is, the positions of the two scatter stations are fixed, and the fixed counterparts are aligned and tracked through the antenna on the carrier. The alignment between the two antennas can be achieved by adjusting the azimuth and elevation angles of the antennas. [0004] With the wide application of troposcatter communication, since the direction of scatter communication is not fixed, both the opposite en...
