摘要
以非相干信号源为研究对象,综合分析了单基地互质阵多输入多输出(MIMO)雷达的波达方向(DOA)估计性能。首先,在总结归纳互质阵结构特点的基础上推导了基于和联合阵列及和差联合阵列的单基地MIMO雷达测向信号模型,然后结合多重信号分类(MUSIC)算法,分别详细介绍了基于和联合阵列及和差联合阵列的单基地MIMO雷达DOA估计方法,最后,进行与等阵元数的均匀线阵MIMO雷达的对比仿真实验,验证了互质阵MIMO雷达DOA估计性能的优越性。
Taking the incoherent signal source as the research object,this paper comprehensively analyzes the performance of Direction of Arrival(DOA)estimation of the monostatic coprime array MIMO radar.Firstly,the direction finding signal model of monostatic MIMO radar based on sum coarray and sumdifference coarray is derived on the basis of summarizing the structural characteristics of the coprime array.Then,by using the Multiple Signal Classification(MUSIC)algorithm,the DOA estimation methods of monostatic MIMO radar based on sum coarray and sum-difference coarray are introduced in detail respectively.Finally,through simulation experiments,a comparison with the uniform linear array MIMO radar with the same number of elements is conducted,which verifies the superiority of the DOA estimation performance of the coprime array MIMO radar.
