Abstract
To further solve spectrum congestion and improve spectrum utilization efficiency, we research a novel integrated radar communication and jamming (IRCJ) system based on a multi-input-multi-output (MIMO) platform in this study. We trade off the beampattern matching error, multiuser interference (MUI) energy, and spectrum matching error as the optimization cost function and design an integrated transmitted waveform that can detect radar targets, achieve high-speed downlink communication, and jam enemies simultaneously. Furthermore, we add a constant modulus constraint to ensure the unimodular property of the transmitted waveform. The proposed optimization problem is multivariable, non-convex, and quartic. To tackle this, we develop an iterative algorithm based on a cyclic manner and majorization-minimization (MM) framework. Finally, the simulation results verify the effectiveness of the proposed algorithm.
