Signal Waveforms and Range/Angle Coupling in Coherent Colocated MIMO Radar
Abstract
In this paper, we consider the coherent collocated MIMO radar framework. We show in this paper that the MIMO ambiguity function presents a range/angle coupling for any waveform family except for perfectly orthogonal families that are unrealistic in practice. We then propose a general model for intrapulse coded MIMO waveforms, and we exhibit different waveform families within this model. For each coding scheme, the MIMO ambiguity function is studied and the range/angle coupling characterized. We also compute the corresponding Cramer-Rao Lower-Bounds. Finally real measurements obtained from a MIMO radar permit to confirm the shape of the ambiguity functions for the studied waveforms.
