MIMO radar

This research will focus upon MIMO systems applied to Radar transmitters and receivers. One of the objectives is to find out whether using multiple Radar transmitters and receivers similar to the MIMO wireless communication principle makes any fundamental difference to the RADAR technology. Other potential research areas will be considered are tracking multiple sources using multiple digital-beams and 3-D location identification using geographically separated multiple receive antennas. Furthermore, this research work will also rekindle Radar information theory field which has been laying dormant since 1950’s and may lead to breakthroughs in radar technology.
