摘　　要：通过电子资源的多任务复用来实现资源配置最优化一直是电子技术发展的一个重要方向。通信信道的多用户复用和软件无线电技术是两项标志性的技术发展成果，其核心均是基于数字技术的。涉及到宽频段和大空域应用时，射频前端数字化却是一个技术难题，AMRFC采用了对射频模拟部件实施数字控制的技术途径，这一技术发展方向值得注意。The optimization of electronic resources utilization is consistently a general trend of electronic system technology development. Multi-user multi-complexity of communication channel and Soft-ware Radio technology are two stone-marks in this direction. Their key technologies are based on digitalization. The digitalization of large coverage antenna aperture and wide-band RF front end of electronic systems is a very difficult problem. A new approach with digital control of these analog components has been adopted in AMRFC, which would be paid more attention to concern.
