Document Type and Number:
Japanese Patent JP6693681
Kind Code:
B2
Abstract:
A correlation matrix calculating unit (6) calculates an unnecessary signal correlation matrix. A diagonal load processing unit (7) performs diagonal load processing on the unnecessary signal correlation matrix. A window function calculating unit (8) calculates a window function for obtaining a side lobe characteristic that reduces unnecessary signals on the basis of an unnecessary signal correlation matrix R after the diagonal load processing. A window function applying unit (9) applies the window function to a reception signal vector. A beam forming unit (10) forms a MIMO beam on the basis of the reception signal vector to which the window function is applied and a beam directivity angle.
