摘要：

The purpose of this letter is to investigate the sensitivity relative to the antenna position uncertainties (APUs) for multiple-input multiple-output (MIMO) radar with colocated antennas. Manifold study is introduced to MIMO radar virtual array as an analyzing tool. To assess the importance of each antenna in a MIMO radar system, we extend Manikas's sensor importance function to MIMO radar. Furthermore, to compare the robustness to APUs of different antenna geometries, we extend the overall-system-sensitivity criterion to MIMO radar system. We show that, with the same sensor geometry, MIMO radar has better robustness performance than the corresponding phased array because of waveform diversity.
