Abstract The novelty of MIMO radar is to improve the performance of radar utilizing spatial diversity and waveform diversity. To achieve full diversity, this paper considers the problem of spatio-temporal signal design for MIMO radar based on channel estimation with the clutter statistical properties known. The method obtains the optimized spatio-temporal signal though minimizing the mean-square error of the channel’s linear Bayes estimation. It shows that the optimized spatio-temporal signal is a function of the clutter covariance matrix, which is verified from information theoretical point of view. Finally the simulation results show that the optimized spatio-temporal signal improves the target detection performance.
