Abstract:
1. A radar device comprising: a signal vector-forming unit configured to form signal vectors having elements of a number of N based on waves reflected from an object and received by using a plurality of receiving antennas of the number of N; a submatrix-forming unit configured to (i) calculate N×N covariance matrices based on the signal vectors having the elements of the number of N, (ii) extract N×(N−1) submatrices from the N×N covariance matrices, and (iii) form two of (N−1)th-dimensional submatrices R a regular matrix operation unit configured to calculate a regular matrix Ψ as Ψ=R an eigenvalue decomposition unit configured to calculate an eigenvalue exp(jΦ an angle calculation unit configured to calculate an angle θ
