Visual Simulation for Determining Unidirectional DOAs

摘要

There is the problem of mirror image vagueness when we use MUSIC to find DOAs. This article analyzed the weakness of previous ways to eliminate mirror image vagueness, improved the technique of visual simulation of MUSIC based on orthogonal ULAs. Thus, the unidirectional DOAs were able to be determined directly from the results-showing figure. The technique increases the automation level of determining unidirectional DOAs.
