Performance Enhancement of Array Configurations with DF Algorithms Based for RDF

摘要

Now adays, there are requirements for keeping communication in a perfect state. These requirements need to prevent disabilities that limit communication systems by monitoring spectrum, processing the interference, removing jammers and illegal radio frequency sources. Direction of arrival (DOA) estimation is one of the localization techniques that used antenna array and signal processing to localize the direction of RF sources in the field of Radio Direction Finding (RDF). In this paper, we implement the comparison of DOAs performance together with their different antenna array configurations such as Uniform Linear Arrays (ULAs), Uniform Circular Arrays (UCAs), and Uniform Rectangular Arrays (URAs). From this analysis, different criteria such as high frequency, correlated signal, closely spaced sources, and noise are considered, and the results show the graph of the power of the signals against the scanned angles in 2D and 3D dimensions. Therefore, it is concluded that (ULA) and (UCA) were proved a good performance according to the cases discussed in this article, and MUSIC confirms suitable performance with all simulation cases.
