中文摘要：

该文将四元数理论应用到双基地集中式多输入多输出（MIMO）雷达的角度估计中。文中通过传统数据模型构造四元数矩阵,提出了基于四元数的求根-多重信号分类（Root MUltiple SIgnal Classification,Root-MUSIC）的MIMO雷达中角度估计算法,该算法通过奇异值分解和Root-MUSIC来估计出发射角（Direction Of Departure,DOD）和接收角（Direction Of Arrival,DOA）。该算法的角度估计性能远优于现有文献的方法,并且无需谱峰搜索,复杂度大大降低。仿真结果验证了算法的有效性。

英文摘要：

This paper employs quaternion theory to angle estimation of collocated bistatic MIMO radar.Quaternion model is constructed from the general data model,and the quaternion Root MUltiple SIgnal Classification（Root-MUSIC） algorithm is proposed for angle estimation in bistatic MIMO radar.This algorithm estimates Direction Of Departure（DOD） and Direction Of Arrival（DOA） via Singular Value Decomposition（SVD） and Root-MUSIC.The angle estimate performance of this algorithm is better than the existing algorithm,and the complexity of the proposed algorithm is reduced very much.The simulation results verify the effectiveness of the algorithm.
