【Abstract】 As a wireless communication technology, software defined radio(SDR) can be used in the scenarios of measuring the quality of radio signals and detecting radio signals. First, this paper introduces the characteristics of SDR in the application of radio monitoring and signal source identification. Then the influence of the system architecture of SDR on high quality radio signal reception is analyzed. Teaching example of SDR is given. Finally, this paper summarizes the current SDR developing situation in technology application, system design and engineering practice, and gives the further developing forecast of SDR.更多还原
