Abstract: With the rapid development of software defined radio technology,SDR is more and more widely used in the field of radio monitoring. This paper briefly introduces the working principle of SDR, and focuses on the application of SDR in aircraft flight tracking and shortwave monitoring and direction finding system emerging on the Internet,which can provide useful working thoughts for radio monitoring.
Key words: SDR; radio monitoring and direction finding system
