ANovelDOA estimation Algorithm BasedonEigen Space

Basedon theinvestigation toclassical DOA algorithm (MUSIC andImproved MUSIC), a novel DOA estimation algorithm isproposed whichmakesfull use of signal subspace andnoisesubspace characteristics. The algorithm can achieve notonly DOA estimation butalso information sourcepowerestimation. Thesimulation result reveals that theperformance ofDOAalgorithm isbetter than that ofMUSICandImproved MUSIC.Intheconditions of coherent sourcesandsmall snapshot aswell aslowSNR,the algorithm can still present a favorable DOA estimation performance. Besides, thecomplexity ofthis algorithm isnot
