Estimation of the Directions of Arrival of Distributed Sources in Array Processing
Shen Zhen-kang · Journal of National University of Defense Technology · 2005
AbstrcatMost of the existing methods of high resolution direction estimation rely on the assumption that the signals are from point sources. Thus, the application of the conventional estimation methods to the distributed sources will show grave deterioration in performance. A new model is constructed for the distributed sources, and an estimation method named DIS-MUSIC proposed. The performance of this method is analyzed and computer simulation results show that DIS-MUSIC is of much better performance than MUSIC algorithm.
