针对UWB-MIMO雷达中的多径干扰问题,采用时间反转技术,利用多径环境中丰富的散射来达到高的目标检测概率。将时间反转应用到UWB-MIMO雷达中,推导出其时域模型表达式。与传统UWB-MIMO比较,在检测概率和目标的DOA估计上,加入时间反转处理后的性能优于传统UWB-MIMO。
To overcome multipath interference in UWB-MIMO radar, time reversal is adopted. Time reversal explores the rich scattering in a multipath environment to achieve high target detection probability. Time reversal is combined with UWB-MIMO radar to estimate DOA. The framework and formulation in time-domain are also elaborated. Corn- pared with conventional UWB-MIMO radar, TR/UWB-MIMO radar has an advantage in DOA estimation.
