Abstract
In this paper, we investigated into the problem of target location in a bistatic multiple-input multiple-output (MIMO), whose transmit antennas and receive antennas are electromagnetic vector sensors (EMVS). Unlike the traditional linear scaler-sensor array, a linear EMVS array can offer two-diemensional (2D) direction estimation, thus a bistatic EMVS-MIMO radar provides (2D) direction-of-arrival and 2D direction-of-departure estimation. Besides, it is able to estimate 2D transmit/receive polarization angles of the targets. An propagator method (PM)-based estimator is proposed. Firstly, it estimate the propagator from the covariance matrix. The parameters are achieved via utilizing the estimation method of signal parameters via rotational invariance technique (ESPRIT) and the vector cross-product technique. The proposed estimator is computationally friendly since it does not involving eigendecomposition of high-dimensional data. Also, it may has similar (or even better) parameter estimation accuracy than the current EPSRIT-Like algorithm. Simulation results verify the effectiveness of the proposed PM estimator.
Highlights
Multiple-input multiple-output (MIMO) technique has aroused massive interests in the past few decades, especially in wireless communications and radar systems [1]–[5]
Inspired by the potential ability for 2D direction finding, a bistatic electromagnetic vector sensors (EMVS)-MIMO radar framework was proposed in [37], in which the transmitters are six-component EMVS and the receiver is a single six-component EMVS, and the ESPRIT strategy is adopted for 2D-DOD and 2D-DOA estimation
To tackle the aforementioned problems, a new propagator method (PM)-Like estimator is proposed for bistatic EMVS-MIMO radar
Summary
Multiple-input multiple-output (MIMO) technique has aroused massive interests in the past few decades, especially in wireless communications and radar systems [1]–[5].

Another EMVS-MIMO radar system was presented in [38], whose transmitters/receivers are multiple EMVS. To tackle the aforementioned problems, a new PM-Like estimator is proposed for bistatic EMVS-MIMO radar. Numerical simulations are carried out to show the usefulness of the proposed estimator
