摘要
波束形成作为一种空域滤波技术,可以对听音信号进行净化,但效果不理想,盲分离技术的出现,给听音波束的净化带来新的方法,但由于受到水声环境的限制,盲分离算法在水声信号处理方面的应用还受到许多约束。对几种常用盲分离算法进行分析,并仿真检验其在听音波束净化方面的性能。
As a spatial filter technology, beamforming can purify audition signal, but the performance is not perfect. Blind source separation, as a new method, can be used for purifying beamspace signal, but because of the limits of the environment of underwater, blind source separation is restrained for using in processing acoustic signals. Several blind source separation arithmetics are analyzed , and the performance of purifying beamspace signal is tested.
