Correlation Characteristics of Channels in MIMO Radar

This paper concerns the correlation characteristics of channels in Multiple-input multiple-output (MIMO) radar. We focus on the relation between the antennas spacing and the correlation characteristics of channels considering the extended target and narrow band signals. This paper demonstrates that the higher carrier frequency, larger target, shorter detecting distances and larger antennas spacing will get the lower correlation characteristics of channels in MIMO radar. Simulation results show the conclusion above and the difference between the results from this paper and ones in previous literature.
