Design Of Miniature System For Wireless Beacon

With the development of miniaturization, information and long ordnance munition, the new demands for telemetry is presented. Aiming at the problem of obtaining dynamical parameter in ammunition experimental aviation, this dissertation focuses on the method of multi-target telemetry and tracking based on miniature wireless beacon and the technology in miniature wireless beacon designed.Firstly this paper analyses and compares to the methods of target tracking and telemetry in common use, selects and uses the telemetry system that called'reversed GPS', aiming at the difficulties and challenge of ball cartridge examination and reclaim in these circs that the falling point distribution is random and wide extension, or deviates from the Hpredetermined ballistic trajectory and falling on the midway because of multi-target and long-distance aviation in experimental aviation based on traditional radio directional bearing.Secondly this paper analyzes the research present conditions and development trend of transmitter and miniature wireless in missile at home and abroad thoroughly ,then designs the PCM-CDMA-QPSK system of integrated miniature wireless beacon which based on the technology of CDMA and DUC.At last debugging is done on the hardware circuit of baseband DSSS system for wireless beacon and the correct waveform results have been gained. According to the examination result, the way of multi-target telemetry and tracking is feasible and designed system is credible and availability.
