| Abstract: | Using the principle of VHP Doppler effect, the Multiple Balloons Tracking System (MBTS) cooperated with balloon-borne transmitter has been developed. Multipath transmission error is largely reduced by a circularly disposed antenna array. The principle of design, operation and performance of the system are described. Trajectories of 40 kilometers coverage of dual constant level balloons and horizontal diffusion coefficient of 30km coverage are obtained in the field observation program at the ZhuJiang (Pearl River )Delta in July 1990. Due to the good performance of traking multiple targets at low level, low cost and lightweight, the system would be a new tool for meso- range atmospheric pollution and diffusion monitoring. |
