Spatial Smoothing Algorithm Using Spatial Interpolation Technique in Adaptive Array
공간보간 기법을 이용한 공간평활 적응 어레이 알고리듬
Abstract
Adaptive array systems are hard to remove all the interferences when incident signals are coherent with a desired signal. In this paper, we propose a modified Duvall beamformer, which performs spatial smoothing using spatial interpolation technique to maintain the degree of freedom. The propose algorithm can minimize the loss on the degree of freedom due to spatial smoothing by forming subarrays with interpolated signals. Simulation results show that the proposed algorithm can remove all the interferences while conventional beamformer cannot.
