MIMO radar: From a different perspective

MIMO radar is an emerging topic receiving an increasing amount of attention mostly aimed at developing concepts and understanding potential capability. As an emerging topic MIMO radar doesn´t have an IEEE definition and if taken literally includes many techniques that have existed much longer than the term itself. In this paper we set MIMO in the context of diversity sensing and draw on the physical interpretation implied by differing concepts to explain expected performance. In this way we present MIMO and related techniques as new and largely unexplored series of radar system design freedoms that offer additional capability. This provides a powerful new paradigm based on diversity for future radar sensors with enormous potential when combined with cognitive processing.
