In this paper, we investigate the joint design of transmit waveform and receive filter for colocated Multiple-Input Multiple-Output radar equipped with one-bit digital-to-analogue converters (DACs). The problem is formulated as maximising the output signal-to-interference-plus-noise ratio in the presence of signal-dependent interferences, subject to a discrete constraint imposed by the waveform quantised with one-bit DACs. To cope with the challenging non-convex problem, an alternating maximisation framework is developed to optimise the transmit waveform and receive filter vectors in an iterative manner. More specifically, for a given transmit waveform vector, the analytical expression of the receive filter vector is first derived. Then, by fixing the receive filter, a biconvex relaxation method is employed to tackle the non-convex problem with respect to the transmit waveform vector. The performance of the proposed approach is demonstrated by numerical simulations in different circumstances. |
