摘　　要：针对传统弹载遥测通信系统所使用的分立元器件占用空间比重较大、移植性差的问题,设计了一款基于ZYNQ和AD9364的软件无线电零中频遥测发射机系统。该系统可以对采编器采集组帧后的数据进行DQPSK调制,利用PS端对AD9364进行寄存器配置,调制后的数据通过PL与AD9364之间的LVDS高速数据接口进行传输,在AD9364芯片内部完成上变频、滤波等处理后,经过功率放大模块,利用所设计的柔性天线将数据发送给地面接收站。最后,搭建了遥测发射机测试系统,对遥测发射机进行了调制通信测试,实现了系统的实地收发数据测试。测试表明,该系统有效降低了弹载遥测系统的体积、功耗和重量,而且依托强大的软件可重构性,不仅简化了硬件设计,还提高了设备通用性,传输距离也大大增加。满足了弹载遥测系统的小型化及通用性需求。Aiming at the problems that the discrete components used in the traditional missile-borne telemetry communication system occupy a large proportion of space and have poor portability, a software radio zero-IF telemetry transmitter system based on ZYNQ and AD9364 is designed. The system can perform DQPSK modulation on the data collected and framed by the editor, and use the PS terminal to configure the AD9364 registers. The modulated data is transmitted through the LVDS high-speed data interface between the PL and AD9364, and the up-conversion is completed inside the AD9364 chip. After processing, filtering, etc., the data is sent to the ground receiving station using the designed flexible antenna through the power amplifier module. Finally, a telemetering transmitter test system was built, and the telemetering transmitter was tested for modulation and communication, and the system′s field data transmission and reception test was realized. Tests show that the system effectively reduces the size, power consumption and weight of the missile-borne telemetry system, and relying on powerful software reconfigurability, not only simplifies the hardware design, but also improves the versatility of the equipment, and the transmission distance is also greatly increased. It meets the miniaturization and versatility requirements of the missile-borne telemetry system.
