主　　题：direction of arrival direct sequence ultra wideband fourth-order cumulant 

摘      要：Direction of arrival(DOA)estimation is one of the key technologies in smart antennas in the direct sequence ultra wideband(DS-UWB)*** DOA estimation methods based on narrow-band signals are not suitable for such ***,a fourth-order cumulant-based estimation method of DOA for DS-UWB signal is *** method is set on the frequency domain model of DS-UWB array *** results show that the algorithm is effective and can guarantee adequate estimation accuracy.
