Abstract:

In this paper, we consider the coherent collocated MIMO radar framework. We show in this paper that the MIMO ambiguity function presents a rangeangle 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 rangeangle 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.
