Bearing Accuracy Improvement of the Amplitude Comparison Direction Finding Equipment by Analyzing the Error

Hongsun Yang, Seungcheon Kim, Soonyong Chun

Abstract


warfare system, is a device that detects electromagneticwaves radiated from target radar and measures its angle of arrival.Compared to the phase-comparison method, the amplitudecomparisonmethod has simpler system, and it’s easy tominiaturize; however, relatively, its direction finding is lessaccurate, and it has various factors that occur errors. This papersuggests improving for the DF accuracy of the amplitudecomparisonmethod base on analysis of error type and cause. Also,this paper proves the usefulness of the result through the test thatwe suggest for the polarization error that has the greatest effect onthe amplitude-comparison method’s DF accuracy.
