| Summary: | The modalities of many imaging applications have been advancing toward the MIMO format for
improved efficiency. This paper presents an approach to the implementation of the MIMO
operating modality for FMCW radar imaging systems with multi-element data-acquisition
arrays. The unique characteristics of the software-defined step-frequency FMCW imaging
systems enable the simple and precise orthogonalization procedure through direct spectral
partitioning. This paper includes the description of the data-acquisition hardware of an eighttransceiver
radar imaging system, imaging formation algorithms, MIMO implementation, and
results of laboratory experiments. |
