A method of space source number feature extraction and automatic recognition for underwater targets;
水下目标空间源数特征提取与识别方法
Usually in blind source separation(BSS) and estimation of the source number, the condition is very difficult to satisfy that the number of sensors must be more than or equal to the number of the sources for complex systems.
通常盲源分离以及源数估计均要求传感器数必须大于或等于源数,对于实际复杂系统来说,这个条件很难满足。
