介紹了一種干涉儀測向機(jī)中相位差提取的方法和多普勒測向原理相結(jié)合的雙通道多普勒測向機(jī)，它可以采用兩部獨(dú)立同型號的接收機(jī)實(shí)現(xiàn)對寬帶信號測向。在闡述雙通道多普勒測向機(jī)基本原理的基礎(chǔ)上，給出了對調(diào)頻信號進(jìn)行測向的計(jì)算機(jī)仿真結(jié)果和部分外場測向試驗(yàn)數(shù)據(jù)，理論與實(shí)測表明：該則向機(jī)測向方法簡單、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.
