摘要
设计了一种基于软件无线电(SDR)平台GNURadio便携式频谱分析仪,给出了完整的设计方案。频谱分析仪由天线、收发转换开关、射频前端、中频接收、ADC、混频器、抽取滤波、DSP、移动客户端显示、云端存储组成,采用HackRF One作为信号处理模块的射频中频硬件平台。该分析仪具有频率分辨率可调、频带宽、便携性好、灵活性强等特点,可广泛用于实验教学。
This paper designs a handy spectrum analyzer based on GNURadio which is a platform of SDR,and presents the complete design scheme.Spectrum analyzer contains antenna,receive or launch switch,RF front end,IF receiver,ADC,Frequency mixer,decimation and filter,DSP,mobile client,cloud storage.HackRF One is used to hardware platform of RF and IF signal processing.Spectrum analyzer has some characteristics such as frequency resolution is adjustable,portability is good,flexibility is good,support bidirectional exchange of receive and launch.Its price is cheap and can be widely used in experimental education.
