Abstract Adaptive space-time coding design is investigated for improving the detection performance of MIMO array radar, with multiple targets and space-time correlation property of clutter RCS considered in this paper. Optimal principle and two suboptimal principles are derived for adaptive space-time coding design, and the interrelation among the three principles, orthogonal space-time coding design and beampattern matching design is clarified. The numerical simulations show that all of the adaptive space-time coding vectors designed by the three principles can significantly enhance the signal-to-clutter plus noise-ratio at the output of the detector, and thus improve the detection performance of the MIMO array radar.
