Multiple-Input-Multiple-Output (MIMO) radars with colocated transmit and receive antennas offer the advantage of a larger (virtual) aperture compared to a conventional Single-Input-Multiple-Output (SIMO) radar. Hence a higher accuracy of the estimated direction of arrival (DOA) of a target can be achieved. In general, the accuracy of DOA estimators(More)
A Multiple-Input-Multiple-Output (MIMO) radar can achieve a higher accuracy in direction of arrival (DOA) estimation compared to a corresponding Single-Input-Multiple-Output (SIMO) radar due to its larger virtual aperture. If the target is moving relative to the radar, an additional phase shift is introduced into the baseband signal because of the Doppler(More)
Multi-carrier (MC) multiple-input multiple-output (MIMO) radar was recently applied to build sparse virtual arrays with a large aperture for a high-accuracy direction-of-arrival (DOA) estimation. The resulting grating lobes (DOA ambiguities) were resolved using multiple carriers. One problem of MC-MIMO is the coupling of the unknown parameters range and(More)
