Description

Technical Field

[0001] The present invention relates to the technical field of relay communications, and in particular, to a microwave relay communication system and a communication method based on a tethered balloon. Background Art

[0002] Microwave communication has the advantages of wide bandwidth, low susceptibility to interference, flexible use, strong gain, strong directionality, low investment, fast construction, and the ability to cope with various complex geographical environments. However, it will be reflected or blocked when encountering obstacles, and is mainly used in line-of-sight communication. Beyond-line-of-sight microwave communication requires relay forwarding.

[0003] The current relay platforms mainly include satellite relay and drone relay. Satellite relay has the advantages of large coverage, long communication distance, stable and reliable lines, and flexible bandwidth allocation, but it also has disadvantages such as high cost, complex technology, large delay, and being greatly affected by climate and geographical environment. Compared with satellites, drones are flexible, low cost, and easy to maintain, but they have problems such as limited payload and limited flight time.

[0004] In complex environments such as disaster relief and exploration, satellite communications cannot be directly carried out due to external reasons such as the geographical environment. The smoothness of information transmission is not guaranteed, which can easily affect the transmission of information. Therefore, there is an urgent need for a transmission system and a transmission method with strong adaptability to the information transmission environment, a wide coverage range, multiple types of transmitted information, strong transmission object and information security capabilities, and strong transmission reliability and timeliness. Summary of the invention

[0005] In order to solve the problems existing in the prior art and ensure smooth information transmission, the present invention provides a microwave relay communication system and a communication method based on a tethered balloon.

[0022] S400, the ground communication receiving end processes and judges the received information, and returns the processed and judged information to the communication relay station, which then feeds the processed and judged information back to the ground communication sending end via the tethered balloon microwave relay.

[0023] The beneficial effects of the present invention are:

[0024] (1) The transmission environment has strong adaptability. The tethered balloon microwave relay provided by the present invention can provide information transmission relay guarantee for complex environments such as emergency rescue and exploration, and can be applied to special geographical environments that are difficult to cover by satellite relay and fixed communication relay stations.
