Abstract:

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.
