A Method of Blind Separation for the Single Vector Hydrophone

A method of blind signal separation based on second order statistic analytic equations is provided for a single hydrophone. This method takes second order statistics equations as restrictive conditions to construct blind separation criterion, then traditional blind separation methods are used to separate source signals through iterative optimization of genetic algorithm. Simulation demonstrates effectiveness of algorithm and separation performance. Results showed: this method can both separate source signals and estimate parameters such as DOA, intensity. And it not only separate incoherent source signals, but also separate source signals which their frequency spectrum are overlapped each other.
