MIMO radar waveform design involving receiving beamforming

Abstract

Multiple-input multiple-output (MIMO) radar has been intensively studied recently and an interesting issue is to design waveforms for a desirable transmitting beampattern and a low sidelobe level. In this paper, for a given colocated MIMO radar system, we propose an algorithm that takes the receiving beamforming into consideration in waveform design. With cross-correlation sidelobes suppressed in receiving beamforming, the optimization algorithm can places more degrees of freedom on suppressing other components and thus a better result can be obtained. The performance of this method is evaluated for both omnidirectional and directional transmitting beampatterns.
