Since　the　two-dimensional　MUSIC　algorithm　has　a　large　amount　of　computation　and　slow　computation　when　estimating　the　angle　of　arrival,　a　two-dimensional　MUSIC　spectral　peak　search　algorithm　was　proposed　based　on　chicken　swarm　optimization　(CSO).　This　optimization　combined　the　chicken　swarm　algorithm　with　the　MUSIC　algorithm　and　the　CSO　algorithm　was　applied　to　the　spectral　search　part,　and　the　angle　corresponding　to　the　spectral　peaks　was　searched　rapidly　with　a　better　searching　capability　of　CSO.　Simulation　experiments　show　that　the　CSO　can　effectively　overcome　the　computational　complexity　and　huge　volume　of　computation　complexity　in　spectral　peak　search　and　by　comparing　with　other　bionic　algorithms,　the　CSO　has　quicker　convergence,　greater　stability　and　better　accuracy.　©　2018,　Editorial　Department　of　Journal　of　Beijing　University　of　Technology.　All　right　reserved.
