In order to achieve lightweight and high-speed wireless transmission of images in the tethered balloons observation system, hardware architecture ZYNQ+AD936 orthogonal frequency division multiplexing technology was adopted. The digital interface with AD9361 RF front end, the ARM part data channel with ZYNQ, as well as the physical layer of baseband processor based on IEEE802.11a standard could be realized through FPGA part of ZYNQ. The ARM section ran the Linux operating system, where the development of AD9361 configuration applications, physical layer management, and data interaction with the host computer and the camera could be achieved. The introduction of wireless image transmission system accomplished the point to point wireless image transmission between the air balloon observation platform and the ground control center, enhancing the reliability of tethered balloons target monitoring observation system. The proposed communication system combined the merits of software radio system, flexible configuration and orthogonal frequency division multiplexing spectrum of high utility and anti-multipath effect, thus it could be applied to a variety of complex environments with the tethered balloon observation system.

Key words: tethered balloons, wireless image transmission, OFDM, AD9361, software defined radio, communication, ZYNQ
