In this study, a multiple-input multiple-output (MIMO) radar system is proposed. It is a time-slotted interactive MIMO radar system that operates in a time-division manner. Based on the proposed system, the authors designed a phase synchronisation algorithm that achieves phasesynchronisation at the target by taking only one extra timeslot regardless of the number of antennas of the MIMO radar system. The authors compared conventional phase synchronisation algorithms, including the master-slave algorithm and time-slotted round-trip algorithm, with the proposed algorithm, the latter of which showed superior performance with low overhead. More generally, the proposed phase synchronisation algorithm was extended to address a moving target by introducing an amendatory factor that can effectively compensate the phase mismatch caused by the target motion. Theoretical expressions of the probability of detection of the proposed algorithm were derived. The simulation results were consistent with the theoretical results and revealed the superiority of the proposed algorithm.
