Direction of arrival(DOA) estimation of coherent sources is always a complex problem.This paper is concerned with the DOA estimation approaches of cyclostationary signals and coherent sources based on a uniform circular array.By using the method of the mode space transformation algorithm and the matrix decomposition algorithm which combines the cyclostationary signals and cyclic MUSIC algorithm,the DOA estimation of the uniform circular array and coherent sources in a Gaussian white noise environment can be realized.The simulation shows the method is efficient.
