.1 Ghz-2ghz Radio Spectrum Analyzer System Design And Simulation

Radio spectrometer is important method and main instrument of radio astronomy research, through which we can research radio astronomy phenomenon in wide frequency spectrum and continuous time with high frequency resolution and high temporal resolution.Radio software techniques and DSP techniques are widely applied in the design and manufacture of modern electronic system. Radio spectrometer based on radio software techniques and DSP techniques has many merits:1. high frequency resolution and high temporal resolution.2. tuneable technical index.3. changing analysis function.Here in the main content of this thesis:1. Radio astronomy.2. Radio spectrometer theory analysis.3. IGHz - 2GHz radio spectrometer system design.4. IGHz - 2GHz radio spectrometer simulation.Software radio spectrometer is newly and audacious attempt in radio astronomy. It is gained high appreciation and high opinion in radio astronomy international co-operation research project and experters believe that it expands radio spectrometer field and it is typical represent of new generation radio spectrometer.
