| 摘 要： | 该文利用2维圆形散射点模型，研究了窄带频率和空间分集MIMO雷达接收通道中的目标回波的统计特性，结果表明目标回波信号本身服从高斯分布，目标回波信号之间的相关系数是等效频率间隔和目标尺寸的函数，空间分集雷达和频率分集雷达的区别在于等效频率间隔的定义。基于散射点模型的数值试验表明该相关系数是有效的。

| 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. |
