In this study, isotropic V-shaped uniform and nonuniform arrays are considered. An isotropic array has the same value for the Cramer-Rao bound (CRB) for all direction of arrival (DOA) angles. The conditions for isotropic V-shaped arrays are presented and closed form expressions for V-shaped uniform and nonuniform arrays are found. These expressions return the V-angle for the array. Therefore, given the number of sensors and sensor displacements, isotropic performance V-angle can be found easily. V-shaped arrays are compared with circular arrays and it is also shown that both uniform and nonuniform V-shaped arrays have certain advantages.

Uniform and Non-Uniform V-shaped Arrays for 2-D DOA Estimation
Filik, Tansu; Tuncer, Temel Engin; Yasar, T. Kaya (2008-04-22)
In this study, a new method for optimum design of uniform and non-uniform V-shaped arrays is presented for azimuth and elevation angle estimation. The proposed design method finds an optimum angle between the linear sub-arrays of the V-array by using the Cramer-Rao Bound (CRB) where statistical coupling effect between azimuth and elevation angle estimation is considered This method can be used to obtain directional and isotropic angle performances for uniform and non-uniform V-arrays. For non-uniform isotro...
Partly-filled nonuniform linear arrays for DOA estimation in multipath signals
Tuncer, Temel Engin; Friedlander, Benjamin (2007-04-20)
Partly-filled nonuniform linear arrays (PFNLA) are presented and DOA estimation problem for multipath signals is investigated. A new approach is proposed for DOA estimation in nonuniform linear arrays (NLA) based on array interpolation. A Wiener formulation is used to improve the condition number of the mapping matrix as well as the performance for noisy observations. An initial DOA estimate is obtained by using the uniform part of the PFNLA. This initial estimate is used in array interpolation and a new co...
Sparse linear sensor arrays: analysis of recent coarray based arrays and array design for nonlinear processing
Epçaçan, Erdal; Çiloğlu, Tolga; Department of Electrical and Electronics Engineering (2021-9-09)
In this thesis, sparse linear sensor arrays have been studied. The study of sparse arrays in this work can be considered under two main headings: Analysis and comparison of recently proposed coarray based arrays, and the adaptation of the nonlinear apodization method for linear arrays and its use in sparse linear array design. Recently proposed coarray-based sparse arrays are designed with closed form structures without the need for any optimization and have much higher degrees of freedom (DOF) than a unif...
Design and evaluation of V-shaped arrays for 2-D DOA estimation
Filik, Tansu; Tuncer, Temel Engin (2008-04-04)
A new method for optimum design of V-shaped arrays is presented for azimuth and elevation angle estimation simultaneously. The design criterion is based on the Cramer-Rao Bound (CRB) for joint estimation where the coupling effect between the azimuth and elevation direction of arrival (DOA) angles is taken into account. The design method finds an optimum angle between the linear sub-arrays of the V-array. The computation of the optimum angle is simple due to the monotonic characteristics of the best and wors...
Direction finding with a uniform circular array via single snapshot processing
Koc, AT; Tanik, Y (1997-01-01)
In this work a new algorithm for multiple emitter direction finding by using a uniform circular array is proposed. The algorithm is based on single snapshot processing, and therefore, it has no restriction on the coherency of the sources. The problem formulation is based on the transformation of the snapshot. The transformed sequence is formed by taking the discrete Fourier transform of the snapshot and weighting it suitably. It contains the so-called distortion terms, which are taken into account by using ...
