The technology and application of wideband real-time spectrum analysis

 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, general system architecture, basic principle and key technologies. At the third section of the paper, some applications are provided. Finally, with the deepening application on signal monitoring and detection, and with supplement of some new theoretical methods, wideband real-time spectrum analysis should be promoting in wide area.
