Guolong Liang, Zhibo Shi, Longhao Qiu, Sibo Sun and Tian Lan

Direction-of-arrival (DOA) estimation in a spatially isotropic white noise background has been widely researched for decades. However, in practice, such as underwater acoustic ambient noise in shallow water, the ambient noise can be spatially colored, wh... ver más

Yu Hao, Nan Zou and Guolong Liang

Capon beamforming is often applied in passive sonar to improve the detectability of weak underwater targets. However, we often have no accurate prior information of the direction-of-arrival (DOA) of the target in the practical applications of passive son... ver más
