Unmanned Aerial Vehicle Real-time Monitoring System Development

this dissertation gives a deep investigation of tactical Real-time Monitoring system and main contributions are as follows:1. On the base of Emulation Techniques, This paper proposed the system function, the key indicator and the system principle. In the last, the basic model of Real-time Monitoring system is builted.2. The design scheme of BD-1/SINS Navigation system is proposed. Locations of each UAV that engaged in tactical training should be obtained and reported in time. Consequently, navigation is necessary and the navigation accuracy can't be significantly improved merely rely on inertial devices. The integrated navigation and data fusion techniques are investigated. The Kalman model of GPS/INS is built and the performance of this system is simulated.3. Communication protocol and terminal device of wireless data link are another two critical techniques of tactical countermine training assessment. The position, velocity, state of target airplane are obtained by spread frequency data link terminal radio and inputted into the simulation computer with the position information of lacal UAVs. The synchronization algorithm of spread frequency is researched and the parallel frequency code synchronization algorithm is proposed. To improve the anti-jamming ability of radio, several fault tolerant control encode mechanisms are analyzed. The implementation method of TURBO with the shortest ring length is put forward.
