摘要
集成电路技术的发展和应用,促使航空遥测系统不断向小型化发展,急需一种新方案代替传统微波通信所使用的分立器件设计方案,而AD9364捷变收发器正是新一代软件无线电单芯片解决方案的杰出代表。介绍一种基于AD9364和FPGA的软件无线电遥测系统,其在采集到遥测数据后先进行组帧和PCM-FM调制,然后将调制信号传给AD9364直接上变频,最后通过飞行器上携带的微带天线发射给地面站。该系统已在多个型号项目上应用,具有集成度高、体积较小、功耗较低、兼容性强等优点,满足航空遥测系统的小型化需求。
The development and application of integrated circuit technology make the aeronautical telemetry system develop continuously to miniaturization, and a new scheme is urgently needed to replace the design scheme of traditional microwave communication. AD9364 agile transceiver is an outstanding representative of the new generation software radio single chip solution. In this paper a software radio telemetry system based on AD9364 and FPGA is introduced. The telemetry system carries out the framing and PCM-FM modulation after the telemetry data collection. The modulated signal is transmitted to AD9364, which realizes the direct up conversion. Finally the microstrip antenna on the aerocraft sends the modulated signal to the ground station. The system has been applied to projects in several types. It has the advantages of high integration, small volume, low power consumption and strong compatibility, which meets the need of aeronautical telemetry system miniaturization.
