【Abstract】 Based on the 2 D model,the case of DOA estimation in presence of complicated noise is studied in this paper.Focusing on the cyclostationary signal,widely existed in practice,a new method using cyclic statistics is proposed.It is the insensitivity to any stationary additive and multiplicative noise that makes it more practical.更多还原
