Technical Field

[0001] The invention discloses a lightweight scattering communication-in-motion antenna device, which belongs to the technical field of communication and is suitable for scattering communication stations at both ends to perform scattering communication in a mobile environment. Background Art

[0002] Due to the Rayleigh fading characteristics of the scattering channel, the signal reception is weak when the communication distance is long. Traditional scattering antenna devices are limited by the narrow antenna beam angle, insufficient real-time antenna alignment, and the inability to maintain posture stability in a mobile environment. They can only be used in application environments such as "communication in stillness" and "communication when stopped", but cannot support scattering communication in a mobile environment, which greatly limits the application field of scattering communication. Summary of the invention

[0010] The azimuth driver invention 7 and the elevation driver invention 8 are both connected to the antenna control unit invention 10, and are used to drive the antenna to rotate horizontally and vertically respectively;

[0011] The inertial navigation system invention 9 is fixed on the antenna base and connected to the antenna control unit invention 10 to upload the device attitude data to the antenna control unit invention 10.

[0012] Furthermore, the equipment monitoring unit 11 is used to monitor the parameter status of the lightweight scattering mobile communication antenna device, and before the scattering communication link is established, it interacts with the opposite scattering communication station through Beidou short messages. After the scattering communication link is established, it interacts with the opposite communication station through the scattering communication link, calculates the communication azimuth in real time according to the position information of the communication stations at both ends, and sends the calculated communication azimuth and the positioning and orientation data reported by the Beidou host 6 to the antenna control unit 10.

[0013] Furthermore, the antenna control unit 10 controls the azimuth and pitch angles of the antenna by controlling the azimuth driver 7 and the pitch driver 8, and adjusts the azimuth and pitch angles of the antenna in real time according to the overall posture data of the device reported by the received inertial navigation system 9 and the positioning and orientation data and communication azimuth data sent by the equipment monitoring unit 11, so that the posture of the scattering parabolic antenna in the mobile environment remains stable, thereby achieving the stability of the scattering communication link.

[0014] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0015] 1. The present invention uses the overall attitude data of the device provided by the inertial navigation system to adjust the azimuth and pitch angles of the scattering parabola antenna in real time in a mobile environment, so that the absolute direction angle and pitch angle of the scattering parabola antenna remain stable during the movement.
