Abstract
In this paper, we consider the joint optimization of transmit waveforms and receive filters for Multiple-Input Multiple-Output (MIMO) radar which deploys one-bit digital-to-analog converters (DACs). We aim to design the transmit signal by maximizing the output signal-to-interference-plus-noise ratio (SINR) in the presence of signal-dependent interference embedded in white Gaussian disturbance. To solve the non-convex problem, we devise an alternating direction multiplier method (ADMM) framework based on the sequential optimization algorithms. Furthermore, an auxiliary variable is introduced to relax the discrete one-bit constraint to continuous interval. Finally, we can obtain a high-quality one-bit transmit signal. Numerical simulations demonstrate that the proposed method can effectively achieve satisfactory performance.
