Abstract：Statistical properties of radar target echoes is researched on narrowband frequency diversity and spatial diversity MIMO radar, with a two-dimensional round shaped scatters model. The results show that target echo in any receiving channel follows a Gaussian distribution and the correlation coefficients between target echoes are functions of the Equivalent Frequency Interval (EFI) and the target size. Spatial diversity and frequency diversity radar are different in the definitions of EFI. Numerical experiment based on scatters model verifies the effectiveness of the correlation coefficients.
