<p>In a beam forming method of the present invention, a steering vector is obtained by using a direction range without using a particular estimated angle of arrival. In order to obtain a steering vector, first, a correlation matrix with respect to an array response vector obtained through integration in a direction range is obtained, the obtained correction matrix is eigen-decomposed to calculate eigen vectors, and a minimization problem for obtaining a steering vector is defined by using a partial eigen vector having small correlation with the array response vector with respect to a desired signal among the eigen vectors. The minimization problem is standardized to a semidefinite program (SDP) and a solution is obtained effectively through a well known method.</p> |
