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
1 軟件無(wú)線電工作原理
軟件無(wú)線電,就是采用軟件數(shù)字信號(hào)處理技術(shù),在可編程控制的通用硬件平臺(tái)上,利用軟件來(lái)實(shí)現(xiàn)無(wú)線電臺(tái)的各部分功能,包括前端接收、中頻處理以及調(diào)制解調(diào)等,都由軟件編程來(lái)完成。(剩余2275字)
