spatial character

According to the spatial character of underwater acoustic signal in far field, a virtual channel is constructed from the observed channel by time delay and filtering. So one single channel is extended to multiple channels, and then the standard BSS methods can be applied.

该方法依据水声信号远场的空间分布规律，通过将单观测通道信号延时和滤波的方法构造虚拟通道，使单通道转化为多通道，以实现单通道的盲源分离。
