Abstract
In this paper, we propose an efficient algorithm based on second order cone programming (SOCP) to design waveform for time-division-multiplexing (TDM) multiple-input-multiple-output(MIMO) radar systems. To this end, we optimize Peak Sidelobe Level (PSL) of the transmit sequence with constant modulus constraint. Indeed, the optimization problem is non-convex and NP-hard, where using semidefinite programming (SDP), we convert it to a convex optimization problem and obtain the optimal set of sequences. The designed waveform is unimodular, and thus appropriate to use in active sensing, where power amplifiers (PAs) are constrained to work in saturation, i. e., transmitting constant amplitude waveforms. Numerical results shows the superiority of the proposed algorithm in comparison with the state of the art.
