The MIMO radar MIRA-CLE Ka

MIRA-CLE Ka is a stationary imaging radar system without moving parts which uses 16 transmit and 16 receive antennas to form 256 virtual antenna elements during signal processing. The system is intended to be used as a mobile imaging, change detection and live sign detection radar for risk monitoring and disaster management. Particular the observation of instable hillsides nearby villages and infrastructures and also the work hillsides and boundary hillsides in daylight mining benefits from a 24/7 weather independent monitoring system. In cases of disasters and catastrophes, MIRA-CLE Ka can be used to secure search and rescue teams to warn for sliding debris and possible collapsing ruins. Also injured people can be detected and localized by the small motion of their chest due to breathing. The benefit of this system is to reduce the complexity, weight, and cost of a fully electronically multi mode radar system compared to common phased-array systems. In this paper we present first proof-of-concept imaging and change detection results obtained with MIRA-ClE Ka.
