Embodiment Construction

[0019] refer to figure 1 , figure 2 . In the following preferred solar UAV embodiment, the distributed mobile-in-motion lightweight shaped antenna mainly includes several distributed front-ends 9, distributed optical fiber signal network 6, distributed low-frequency signal network 7, and distributed grating sensors Network 8, wherein the centralized processing terminal 10 is located in the middle position above the fuselage along the course. The solar panels 11 are arranged in a linear array on the wing surface, and several distributed front ends 9 are arranged on both sides of the solar panel 11. Each distributed front end 9 can be formed in different positions of the large-scale wing, and the distance between adjacent ones can be arbitrary, and can be designed according to the specific position of the wing, wherein each distributed front end 9 includes a silicon-based integrated The transceiver chip 2 is electrically connected to the distributed antenna sub-array 1 , the...

Abstract

The invention provides a distributed communication-in-motion light shaped antenna which is composed of a plurality of distributed front ends (9), a distributed optical fiber signal network (6), a distributed low-frequency signal network (7) and a distributed grating sensor network (8). Each of the distributed front ends comprises a distributed antenna sub-array (1), an electro-optical / photoelectric conversion chip (3), a sub-array wave beam control system (4) and a grating sensor (5), which are electrically connected around a silicon-based integrated transceiver chip (2). Under command control of a centralized processing terminal (10), each distributed front end (9) can implement beam scanning and satellite signal alignment; and then the plurality of distributed front ends (9) implement beam forming and real-time satellite communication under command control of the centralized processing terminal (10). The technical problem that the existing communication-in-motion antenna is designed in an integrated mode in an aperture, is large in size and heavy, and is hard to match a flexible wing structure in stiffness is solved.

Description

technical field [0001] The invention relates to a mobile satellite communication antenna (antenna in motion), which is suitable for mobile carriers to automatically capture and track satellites in real time, and to provide high-speed, broadband and large-capacity voice, data and high-definition dynamic video images and other multimedia information satellites Communication system, especially for satellite communication system of solar drone. Background technique [0002] Mobile-on-the-Move is the abbreviation of "Satcom-on-the-Move (SOTM)". Satellite mobile communication in motion is a technology that uses geostationary orbit satellites or medium and low orbit satellites as relay stations to realize communication between ground, air, and sea mobile users or between mobile users and fixed users. Fields such as military communications, anti-terrorism and anti-smuggling at sea are playing an increasingly important role. In the "communication in motion" satellite communication ...
