针对用户对背负式短波数字化抗干扰电台的体积缩小要求,提出了一种采用软件无线电(SDR,Software Defined Radio)技术,通过对中射频全数字化最终形式,设计了一款手持短波软件电台。主要研究了短波数字化抗干扰电台到手持短波软件电台的体系与结构解决方案,解决了手持短波软件电台体系框架建设与结构体积压缩及电磁兼容等问题。实现了手持短波软件电台系统与结构小型化方案,并对系统和结构进行了研究、分析、试制、总结,最终达到了实际使用和开发产品应用目的。
In order to reduce the size of the shortwave digital anti-jamming station, this paper presents a hand-held shortwave software station designed by using SDR (Software Defined Radio) technology. Mainly studied the shortwave digital anti-jamming radio to handheld shortwave software system and structure of the solution, to solve the shortwave software radio system architecture and structure of the volume compression and electromagnetic compatibility issues. The implementation of hand-held shortwave software radio system and structure miniaturization program, and the system and structure of a research, analysis, trial production, summary, and ultimately reached the actual use and development of product applications.
