| Abstract: | Expressions on several spatial spectrum of irrelevant sources such as Capon and Music based on electromagnetic vector sensor array are derived.Compared with the spatial spectrum of scalar sensor array,the improvement of DOA estimating method on the basis of vector sensor array is analyzed.Single electromagnetic vector sensor array is analyzed and DOA estimation in terms of the principles of array signal processing.It is proved that the resolving power of vector sensor array DOA estimation is stronger than that of scalar sensor array through computer emultion. |
