| 摘 要： | 多输入多输出(MIMO)霄达足近几年发展起来的一种新慨念雷达体制.为了进一步降低宽带MIMO雷达的阵列规模和硬件复杂度,使MIMO雷达成像技术实用化成为可能,结合改进型后向投影(BP)成像算法,提出了一种非均匀线阵成像系统阵列布阵模型.提出的阵列布阵模型通过成像系统方位向分辨率婴求和目标方位向成像场景大小确定阵元间距,使得系统的阵列规模和硬件复杂度显著降低.同时,时域成像算法的使用避免了频域算法存在的采样定理限制,有效增强了阵列设计的灵活性,并使得成像阵列规模和硬件复杂度得到进一步降低.最后仿真实验验证了该成像系统布阵模型的正确性和有效性. |

| Abstract: | Multiple-input and multiple-output(MIMO) radar is a new radar system developed in recent years.In order to reduce the array dimension and hardware complexity,and make the application of MIMO radar imaging technology come true,a nonlinear array model is proposed,combined with the improved back-projection(BP) imaging algorithm.The proposed array model can acquire the array element intervals by the cross-range resolution requirement of imaging system and the choice of the imaging scene,and so can reduce eviden... |
