For the target echo correlation, the existing target model has a huge limitation which just represents the angle or frequency interval with respect to the station, but ignores the influence of target attitude. To solve this problem, this paper utilizes the four straight prism scattering model to better simulate the true target, and the research shows that the correlation coefficient is affected by the observed direction, target size, spatial and frequency interval at the same time in the diversity MIMO radar. The study focuses on the variation of the target's effective size with the observed direction and spatial size in the case that the radars stay at different positions, which influences the correlation coefficient severely
