Abstract

The invention discloses a relay communication system and method based on a UAV platform. The system includes: a ground communication terminal and a UAV-borne relay communication platform. The UAV-borne communication platform is set on the UAV for To forward the data transmission between different ground communication terminals, the UAV-borne relay communication platform adopts an airborne antenna with a beam width of 160 degrees, the gain is 3-5dBi, and the radio frequency power amplifier power is 10 watts; The communication platform to the ground communication terminal is a point-to-multipoint communication method, and data is transmitted based on time division multiplexing, and the ground communication terminal to the UAV communication platform is a multipoint-to-point communication method, using TDMA Data is transmitted in multiple access mode. The system greatly increases the effective coverage area of ​​communication; at the same time, it makes emergency communication in complex terrain more efficient and convenient, and realizes that the wireless link can still communicate normally in the case of non-line-of-sight.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a relay communication system and method based on an unmanned aerial vehicle platform. Background technique [0002] The transmission of information has become an indispensable part of today's social life, but the construction of communication networks in some special areas is still very fragile, especially in the event of natural disasters and wars, some information will be lost due to damage to communication facilities or interruption of communication. The emergence of isolated islands. [0003] For the communication problem between multiple different terminal nodes in the region, there are many solutions in the prior art, for example: through the geostationary orbit satellite communication system, through the maritime satellite communication terminal, through the radio network, through the Wi-Fi network, etc. etc. to achieve communication between different terminal node...
