Comparison and tests of different virtual arrays for MIMO radar applications

Traditionally well-known from communication applications, the multiple-input multiple-output principle (MIMO) has found its way into radar system theory in the last years. Different arrangements of transceivers equipped with orthogonal signals, lead to arrangements of virtual elements which is denoted as virtual array in the context of coherent MIMO approaches. In order to proof practical feasibility of ongoing theoretical considerations, experiments have been started and evaluated.
