Abstract: | An expression for the cross-spectral matrix of the co-array of an element space noise MIMO radar is derived and then used to determine the output power in various noise fields using both conventional and MVDR beamforming. Theoretical and numerical results are presented to show that beamforming using an intuitive form of the cross-spectral matrix of the co-array for noise MIMO radar provides no benefit over receive-only beamforming in the presence of any combination of scatterers, jammers and white noise when constant scattering coefficients are assumed. A time domain formulation is considered and theoretical and simulation results are presented to demonstrate its ability to realize the full gains of the co-array when a sufficient number of samples is used in the temporal component of the MIMO matched filter. © 2011 Elsevier Inc.
