Abstract:Focused on the Direction Of Departure(DOD) and Direction Of Arrival(DOA) estimation of bistatic Multiple Input Multiple Output(MIMO) radar, an estimation method is presented by using wide-band cyclostationary signal. Firstly, an autocorrelation matrix of receiving wide-band cyclostationary signals is constructed. And then eigenvalues of the matrix are decomposed. At last, DOD-DOA are estimated by spatial spectrum estimation algorithm such as MUSIC algorithm or ESPRIT algorithm. Wide-band cyclostationary signal can carry more information, which is increasingly important, and its cyclostationary property restrains Gaussian noise as well as interference from different frequencies effectively. The result of simulation shows that the method has good angle estimation performance with wide-band cyclostationary signals.
