MIMO Radar: A Multi-Sensor Spatially Diverse Radar Architecture
Abstract
The research supported by this grant: (a) provides an in depth analysis of the localization accuracy gain attainable with the MIMO radar systems by means of the Cramer-Rao Lower bound (b) introduces the geometric dilution of precision (GDOP) metric and the contour mapping, providing an insight into the relative performance accuracy for a given layout of radars over a given geographic area. These plots offer a clear understanding of the collaboration effect of different sensor scheme on the resulting accuracy. Furthermore, target localization estimators were developed and evaluated (c) presents the analysis on the ambiguity arising in the high resolution localization due to side-lobe characteristics of the MIMO system and viable solutions to the problem. This report documents our work on MIMO radar with widely separated antennas thus called "distributed MIMO radar". Widely separated transmit/receive antennas capture the spatial diversity of the target's radar cross section (RCS). For target location, it is shown that coherent processing can provide a resolution far exceeding that supported by the radar's waveform.
