摘　　要：宽带实时频谱分析技术主要用于各类宽带辐射源信号的侦察、捕获与分析。本文分析了宽带条件下实时频谱分析面临的挑战,重点分析了宽带实时频谱分析的概念、系统结构、实现原理以及关键技术,介绍了相关技术在频谱监视以及信号侦察中的应用示例,随着应用的深入以及一些新的理论方法的不断完善,该技术在复杂宽带信号分析方面具有很好的应用前景。The technology of wideband real-time spectrum analysis focuses on the effective discovery, capture and detection of signal with the large bandwidth and the complex modulation. This paper first analysis the challenge of wideband real- time spectrum analysis（ RTSA）, then highlights the conception of technology of wideband real-time spectrum analysis, gen- eral system architecture, basic principle and key technologies. At the third section of the paper, some applications are pro- vided. Finally, with the deepening application on signal monitoring and detection, and with supplement of some new theo- Yetical methods, ,sideband real-time spectrum analysis should be promoting in wide area.
