Yuri B. Nechaev, Ilia W. Peshkov

Abstract


Direction-of-arrival (DOA) of radio signals takes a great scientific 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, the problem of false peaks occurring in spatial spectrum is closely considered. Probability of occurring false peaks after computer simulations is presented.
