Abstract: This paper introduces a dual-channel Doppler direction finder which combines the Doppler principle with the phase difference picking method used in the interferometer direction finder. The finder can be implemented with two independent receivers of same model for direction finding of broadband signals. On the basis of the description of fundamental principles of a dual-channel Doppler direction finder, this paper provides the computer simulation results of direction finding against FM signals and partial data from field tests. Theoretical deduction and test results both prove the simplicity and feasibility of the mentioned DF method.
