MIMO-waveforms for GMTI radar - A study on the use of MIMO waveforms to decrease MDV in GMTI radar

Abstract

Abstract This study investigates the use of MIMO waveforms in mitigating the effects of clutter in GMTI radar systems. Clutter, which is any unwanted reflection from the ground with a Doppler shift will affect the performance of a radar. In particular the minimum detectable velocity will increase. By applying MIMO waveforms it is possible to, in some cases, increase performance and decrease the minimum detectable velocity. This study has through simulations explored MIMO systems and compared these to traditional SIMO systems. Furthermore sparse arrays has also been explored and once again compared between MIMO and SIMO. Moreover this study has developed a unified model capable of simulating systems using for example SIMO, MIMO or sparse arrays. This serves as a valuable tool to perform further studies on the topic.
