摘　　要：针对传统软件无线电(SDR)平台的通用性差、面积大、离散化等问题,提出了使用Kintex7 FPGA与双通道射频收发器AD9371搭建一种通用且具有航天应用潜质的SDR平台。本平台与传统平台相比具有较高的适配性,使用嵌入在FPGA中的MicroBlaze、NiosII等软核处理器,通过C语言即可完成相关参数的配置,极大提高了平台对软件和操作系统的兼容性。同时严格遵守PCB设计规则,使平台性能达到最优。通过增益数据对比分析,证明本平台在功耗没有提升的情况下,发射功率明显优于官方评估板,同时极大地提高了工作效率,在无人机、电子战和军用通信等方面都有巨大的应用前景。Aiming at the problems of poor universality, large area and discretization of traditional software-defined radio(SDR) platform, a universal SDR platform with aerospace application potential is proposed by using Kintex7 FPGA and dual channel RF transceiver AD9371.Compared with the traditional platform, this platform has higher adaptability.Using MicroBlaze, NiosII and other soft core processors embedded in FPGA,the configuration of relevant parameters can be completed through C language, which greatly improves the compatibility to software and operating system of the platform.At the same time, it strictly abides by PCB design rules, so that the platform performance is optimized.Through the comparative analysis of gain data, it is proved that the transmission power of this platform is obviously better than that of the official evaluation board without increasing power consumption, and the work efficiency is greatly improved.It has great application prospect in UAV,electronic warfare and military communication.
