| Abstract: | For the eigenstructure-based superresolution direction finding technique,the array sensor gain and phase uncertainties degrade severely its performance.In this paper,we present a new method for superresolution direction finding based on MF sampling and orthogonal filtering technique.The method can keep the array sensor gain and phase certainties and improve the direction finding performances obviously.Computer-based simulations have shown the effectiveness of the method. |
