Orthogonal waveform design for MIMO radar via constrained nonlinear programming

A constrained nonlinear programming method is proposed for designing orthogonal waveforms applied to multiple input multiple output(MIMO) radar systems.The designed orthogonal waveforms are phase-coded signals with a uniform amplitude and arbitrary phases.The optimal orthogonal waveforms have lower auto-correlation peak sidelobe levels(APSL) and lower peak cross-correlation levels(PCCL),compared with those of other methods.Addationally,the relationships among APSL,PCCL and the size of the orthogonal waveforms are studied via numerical experiments.
