Abstract
The conditions for orthogonality in Multiple Input Multiple Output (MIMO) radar enable a virtual array gain beneficial to beamforming on receive. However, this condition imposes a constraint on transmit beamforming for various reasons. As a result, a performance loss can be expected when compared to a traditional monostatic phased array. With this in mind, we analyze the complex scattering coefficients for a scenario in which MIMO radar beamforming is used to illuminate an arbitrary target obfuscated by different line-of-sight obstructions such as foliage and/or buildings. Using finite-difference time-domain (FDTD) modeling, our simulations will grow the understanding of how plausible MIMO radar is for detecting targets in challenging environments.
