Targets Imaging Method for A New MIMO Through-wall Radar

Abstract

Abstract The ultra-wideband (UWB) multi-input multi-output (MIMO) radar technique is playing a more and more important role in the application of through-wall detection because of its high resolution, lower antenna requirements, and efficient data capturing ability. A new UWB MIMO sparse array radar system with eight pairs of transmitting and receiving miniaturized Vivaldi antennas is designed in this paper and reverse time migration of the acoustic wave equation based on finite difference is used for target imaging. How to locate the target and reconstruct velocity model is the key in this paper. Finally, we found that this processing method is completely effective for forward single-target imaging, but there is still a lot of research space, and if we want to apply them in practice, further study must be done.
