The Uav Ground In The Multi-channel Baseband Implementation Study

Because of a Unmanned Air Vehicles(UAV) will be faced with many problems for carrying out tasks,organizing several Unmanned Air Vehicles being in conjunction with carrying out mission will becoming an important campaign method. For increasing the usage efficiency,reducing the equipments and depressing cost of Ground Control Station, Multi-UAVs Controlled by One ground control station(GCS) data link technology is be putted forward.With the advance of phased array antenna technology, Multi-UAVs Controlled by One GCS data link of UAV is more and more mature, howing to realize signal proceeding to several signals of UAV at the time in sing an equipment will play the key role in Multi-UAVs Controlled by One GCS data link.the multi-channel ground bass-band is one of the core to realizes to handle several signals of UAV at the time.This thesis systematically describes the implementation methods of multi-channel ground base-band equipment based on Software Defined Radio (SDR) structure by analyzing the work theory of Multi-UAVs Controlled by One GCS data link.At the first, the research background, the significance and the domestic and foreign situation of UAV technology development are introduced. Secondly the key theoretical knowledge of UAV is expounded.It will analyze from theory the design of Pseudo Noise Sequencey,track receiver,distance measurement by distance and remote control technology. the thesis will consentrate on the specific implementation method of related algorithm of UAV base-band equipment. Furthermore parts of design diagram of key circuit are presented. In addition, the hardware design of multi-channels ground base-band equipment and the specific circuit implementation are provided. At last, we shall discuss the test methods and results of key indicators of multi-channels ground base band equipment.The design characters of multi-channels ground base band equipment will be summarized and introduced the further research work. The result of experimentation shows that the multi-channel ground base band equipment has good consistency and meet the design requirements, which can be used in the Tracking Telemetry and Command (TT&C) of UAV.
