Abstract

The concept of multiple-input multiple-output (MIMO) radar is recently proposed inspired by recent advances in MIMO communications. A recently proposed statistical MIMO radar configuration is considered here, in which the transmit array antennas are widely spaced to enable spatial diversity with respect to the targets, while the receiver is an uniform linear array with the elements spaced half a wavelength apart to enable direction finding. In this proposal, this signal model is extended to the multiple-target case, and the problem of multiple-target localization and estimation is considered. The Capon and APES techniques for multiple-target localization and estimation of MIMO radar systems are proposed in this paper. The performance of the proposed method is validated by numerical simulations.
