Unmanned aerial vehicle, communication method, command and control station, information receipt receiving station and reconnaissance system

Abstract

The invention provides an unmanned aerial vehicle for intelligence information transmission, a communication method, a command and control station, an intelligence receipt receiving station and a reconnaissance system. And the reliability of the system is improved between the unmanned aerial vehicle and the command and control station by using frequency band redundancy. A U-band communication link is quickly established between an unmanned aerial vehicle and a command and control station through an omnidirectional antenna in an initial stage, and then the communication link is upgraded into a C-band communication link capable of meeting a large data volume transmission requirement, so the requirement of earlier-stage link establishment rapidness and the requirement of later-stage large bandwidth are both considered. For the intelligence receipt receiving station, a communication link is rapidly established through an omnidirectional antenna in the initial stage, the communication link is used for receiving azimuth information of the unmanned aerial vehicle, the orientation and the pitch angle of a directional antenna are adjusted through the azimuth information, the communication link is optimized through the directional antenna, and transmission of a large amount of data is achieved. By means of the advantages, the method has wide application prospects in the military and civil fields.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle communication in the wireless communication industry, and in particular to an unmanned aerial vehicle used for intelligence information transmission, a communication method, a command and control station, an information single receiving station, and a reconnaissance system. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agri...

Problems solved by technology

[0003] However, in the process of implementing the present invention, the applicant found that the reliability of data transmission between the UAV and the command and control station is poor. In the case of interference, the channel for the UAV to obtain the control signal of the command and control station may be blocked. Drones may lose contact or be hijacked by the enemy, causing unpredictable risks
