Abstract

Considering the fact that the electromagnetic spectrum is becoming more and more crowded due to the increasing demand for both military and civilian wireless services. A novel MIMO radar transmit beampattern design scheme with PAR constraint in a spectrally crowded environment is proposed. Different with the existing beampattern design methods, the PAR and spectral constraints are considered in the optimization of the space-time transmit waveform covariance matrix. Semidefinite relaxation (SDR) is adopted to tackle the resulting NP-hard optimization problem. With the optimized covariance matrix, the final transmit waveforms which satisfy the practical constraints can be synthesized directly via randomization. Some numerical simulation results are shown to demonstrate the effectiveness of the new technique to devise MIMO radar transmit waveforms in beampattern design complying with the PAR and spectral coexistence requirements.
