<p>A pseudo-spatial-average-covariance-matrix generating unit selects, from matrixes R f1 , R f2 , R b1 and R b2 , one appropriate matrix or two or more appropriate matrixes for combination to generate a pseudo-spatial-average-covariance matrix R. A pseudo-spatial-average-covariance-matrix Hermitian-conjugate product generating unit generates a target-count-estimation matrix RR H . A target-count-estimation-matrix decomposing unit performs LU decomposition on RR H into a lower triangular matrix L and an upper triangular matrix U. An index generating unit generates an index using elements of the upper triangular matrix U. An index-parameter scanning unit estimates a target count by using the index generated by the index generating unit.</p> |
