A Propagator Method for Bistatic Coprime EMVS-MIMO Radar [PDF]
Mathematical Problems in Engineering, 2021 In this paper, a novel two-dimensional (2D) direction-of-departure (DOD) and 2D direction-of-arrival (DOA) estimate algorithm is proposed for bistatic multiple-input multiple-output (MIMO) radar system equipped with coprime electromagnetic vector sensors (EMVS) arrays. Firstly, we construct the propagator to obtain the signal subspace.

Generalized spatial smoothing in bistatic EMVS-MIMO radar
Signal Processing, 2022 Abstract This paper revisits the problem of multiple parameters estimation for coherent targets in bistatic EMVS-MIMO radar. By extending the spatial smoothing mechanism to the EMVS-MIMO radar, three generalized spatial smoothing estimators, named the TS approach, the RS approach and the TRS approach, have been proposed.

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.
