Evaluation of Imperfect Synchronization Effects on MIMO Radars and its Application to Performance Improvement

分析了多输入多输出（MIMO）雷达接收机采样和相位抖动不完全同步对雷达探测性能的影响。发现这些抖动对MIMO雷达的探测概率没有显著的降低。开发了一个超边带（UWB） MIMO试验台进行实验评估。此外，还开发了用于超宽带雷达的高分辨率到达角估计方法。

Effects were evaluated of imperfect synchronization of receivers-sampling and phase jitters-within multiple-input multiple-output (MIMO) radars on their detection performances. These jitters were found to yield no significant degradation to the detection probabilities of the MIMO radars. An ultra-sideband (UWB) MIMO testbed was developed for experimental evaluations. Also, high-resolution estimation methods of angle-of-arrival were developed for use in UWB radars.
