This paper introduces a single channel Doppler direction finding system based on software defined radio (SDR), the system uses digital signal processing method to analyze and process the Intermediate frequency (IF) signal output by radio receiver after A/D sampling, then demodulates the direction of radio incoming wave. The composition, signal processing method and direction finding principle of single channel Doppler direction finding system are described in this paper.
