A method of direction of arrival (DOA) and direction of departure (DOD) angle estimation based on polynomial rooting for bistatic multiple-input multiple-output (MIMO) radar with uniform circular array (UCA) configuration is proposed in this paper. The steering vector of the UCA is firstly ...

A comprehensive study is performed to investigate the performance of a non-uniform circular array interferometer in a real time 3-dimensional direction finder. The angular range of view is supposed to be 65 degrees vertically and 120 degrees horizontally, which is suitable for airborne applications....
a planar array is needed when estimates of source azimuth and elevation are required. Such well-known planar arrays include the two-orthogonal uniform linear array (the L-shaped array) [1], the rectangular array [2], and the uniform circular array (UCA) [3–7]. The UCA is able to prov...
uniform circular vector of array signals,the electromagnetic vector sensor array receiving signal model was established based on quaternion,and joint estimation of the electromagnetic vector sensor array signal's DOA and polarization information using quaternion's multidimensional orthogonal properties and the...
a(θD)] is usually called the array manifold, and its columns are referred to as steering vectors since, as will be shown, they may be used to “steer” the array response in any desired direction. It is assumed that for any set of distinct parameters θi, i = 1, 2, …, D, M...
\begin{aligned} \lim _{\delta \searrow 0}\sup _{\begin{array}{c} x,y \in [a,b] \\ |x-y|<\delta \end{array}} \left| (f(x)- f(y)) \log \delta \right| = 0. \end{aligned} (4) This is a very weak condition, weaker than the Hölder condition for any \alpha >...
针对均匀圆阵的DOA估计,提出了一种改进的Toeplitz解相干DOA估计算法。该算法利用模式空间变换算法,将均匀圆阵变为虚拟均匀线阵,在此基础上利用接收数据协方差矩阵的行、列分别构造Toeplitz矩阵并取均值,以此来改变协方差矩阵的数据结构,使协方差矩阵的秩得到有效恢复,
