WAVEFORM DESIGN FOR ADAPTIVE PHASE-MODULATED OFDM-MI MO RADAR TO IMPROVE DETECTION PERFORMANCE

摘要：

This paper deals with the waveform design of phasemodulated OFDM-MIMO radar to strength the detection performance.A system model for MIMO radar with each transmitter operating at one of the subcarrier frequencies of OFDM signal is developed.The objective function is a quadratically constrained quadratic program (QCQP) problem, which is NP-hard and is not able to be solved in polynomial time.To solve it, a method utilizing semidefinite program relaxation combined with randomization (SDPRR) is proposed to approximate the optimal solution.Simulation results confirm the effectiveness of the proposed method in terms of detection probability.
