双通道多普勒测向机研究

介绍了一种干涉仪测向机中相位差提取的方法和多普勒测向原理相结合的双通道多普勒测向机，它可以采用两部独立同型号的接收机实现对宽带信号测向。在阐述双通道多普勒测向机基本原理的基础上，给出了对调频信号进行测向的计算机仿真结果和部分外场测向试验数据，理论与实测表明：该则向机测向方法简单、可行。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.
