The near-field array response vector at the mm-th subcarrier \bm am(ϕ, r)\bm am(ϕ, r) can be elaborated as \bmam(ϕ,r)=1√N[e−j2πfmc(r(1)−r),…,e−j2πfmc(r(N)−r)]T,(3)(3)\bmam(ϕ,r)=1N[e−j2πfmc(r(1)−r),…,e−j2πfmc(r(N...
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 ...
The Davies transformation is a method to transform the steering vector of a uniform circular array (U CA) to one with Vandermonde form. As such, it allows ... Buon,Kiong,Lau,... - 《IEEE Transactions on Signal Processing》 被引量: 38发表: 2006年 Dummy run and conformity indices in the...
on a uniform circular array.Through introducing an array steering vector,the ability of searching the desired signal beam is obtained by the adaptive array.So the complicated process for direction estimate is avoided.The system scheme is also presented here.Finally,the validity of the algorithm is ...
This study makes use of the UCA heading information and the properties of the UCA steering vector to address this problem. A two-step spatial rotation procedure is devised to rotate the source DOAs from array coordinates to geodetic coordinates in real time, and consequently, the UCA remains ...
1-with ULA only along x-axis, we can estimate elevation angle only 2- Now if we lift this array from x-axis and place it along y-axis, and no other array, then which angle can we estimate with this ULA: elevation or azimuth?

Here, the concepts of the Wavefield modeling for scalar-fields are given. Two expressions for decomposing the steering vector (manifold) of array elements with sparse UCAs are presented. These form the theoretical basis of our algorithm. In [10], it is shown that the array steering vector is ...
