基于酉變換-矩陣束的稀布線陣方向圖綜合
[Abstract]:In this paper, a non-iterative method for pattern synthesis of rarefied linear arrays is proposed. In this method, the data sampled from the square graph is processed by centro- Hermitization, then the equivalent real matrix bundle is constructed by unitary transformation, and the relation between the position of the non-uniform element and the generalized eigenvalues of the new matrix bundle is obtained. On this basis, the singular value decomposition of the real matrix and the abandonment of the non-main singular value to obtain the low-order left singular vector matrix, and then the position of the element and the corresponding excitation of the rarefied array are obtained. Compared with other methods, this method can get the real solution of element position directly. Singular value decomposition (SVD) and eigenvalue decomposition (EVD) are carried out in the real number domain, which improves the degree of approximation and effectively reduces the computational complexity. Simulation results show that the proposed method can efficiently realize the pattern synthesis of linear arrays by using a small number of array elements.
