Computationally Efficient Unitary ESPRIT Algorithm in Bistatic MIMO Radar [PDF]
Mathematical Problems in Engineering, 2021 A low complexity unitary estimating signal parameter via rotational invariance techniques (ESPRIT) algorithm is presented for angle estimation in bistatic multiple-input-multiple-output (MIMO) radar. The devised algorithm only requires calculating two submatrices covariance matrix, which reduces the computation cost in comparison with subspace methods.
