A Study on the Effectiveness of Averaged MUSIC Using Limited Number of Sensors
제한된 수의 Sensor를 이용한 Averaged MUSIC의 효율성에 관한 연구
Abstract
The main purpose of this paper is to verify the effectiveness of a high resolution direction finding method, so called the‘averaged MUSIC’. This method uses a new sample array covariance matrix that consists of diagonal components obtained by taking averages of the diagonal component values of the sample covariance matrix for the MUSIC. The paper shows that the proposed method performs higher resolved direction-of-arrival estimation and better resolution probability than the MUSIC in such cases as low signal-to-noise ratio, when the number of sensors used is finite, based on the statistical analysis.
