Multiband waveform synthesis and detection for a wideband MIMO radar

In the context of wideband Multiple-Input Multiple-Output (MIMO) radar, this paper presents a waveform design technique using multiple frequency bands, satisfying a low Peak-to-Average Power Ratio (PAPR) constraint. We then adapt a Direction-of-Arrival (DOA) estimation technique, known as TOPS (Test of Orthogonality of Projected Subspaces) in the literature, to the received signals in a MIMO radar system.
