- W3210137853 abstract "Wideband two-dimensional multiple input multiple output (MIMO) radar can be used for target three-dimensional (3-D) imaging. As the echo of wideband MIMO radar is derived from both time and spatial sampling, the time-frequency coupling is contained, resulting in imaging defocussing. To solve this problem, a time-frequency decoupling algorithm based on matrix enhancement and matrix pencil (MEMP) is proposed to achieve high-resolution 3-D imaging. By combining the enhanced matrix constructed via MEMP with the modern spectral estimation theory, the time-frequency coupling term is regarded as a space rotation factor and is eliminated in the process of target position estimation. Simulation results show that the proposed algorithm can reduce the negative influence of time-frequency coupling and improve the imaging accuracy of wideband two-dimensional MIMO radar." @default.
