In　recent　years,　the　demand　for　indoor　localization　techniques　has　grown　rapidly.　In　order　to　meet　such　demand,　this　article　focuses　on　indoor　localization　and　proposes　a　novel　application　of　AoA　technology-based　localization　system.　The　main　application　scenario　is　inside　an　underground　garage　with　line-of-sight,　and　a　beam　forming　AoA　positioning　system　is　simulated　using　Matlab.　Finally,　an　outlook　of　applications　based　on　this　system　is　presented.　©　2024　IEEE.
