摘要
Abstract
In the traditional vector data processing methods ,the output of vector hydrophone array is expressed as a complex column vector ,which cannot hold the orthogonality of the inside structure .Here ,biquaternion algebra is employed to model the output of a vector hydrophone ,which holds the orthogonality of the inside structure and is robust to coherent noises .What's more ,in order to cut down the computational complexity and improve resolution power ,biquaternion based DOA algorithm of beam space is introduced .Simulations and comparisons are given at the end ,which verify the efficiency of the algorithm .关键词
