Probability of false peaks occurring via circular and concentric antenna arrays DOA estimation

Direction-of-arrival (DOA) of radio signals takes a great science interest for radar, sonar and wireless communication tasks. In this paper the problem of DOA estimation methods for circular and concentric circular antenna arrays is considered. The super-resolution method MUSIC is researched. The performances are estimated in various noise environments and for various geometries of antenna arrays. Additionally problem of false peaks occurring in spatial spectrum is closely considered. Probability of false peaks occurring is presented after computer simulations.
