in this study, a new design method is proposed for V-shaped planar array geometry for two-dimensional azimuth and elevation angle estimation. The proposed method is similar to filter design in signal processing. This method determines the V-shaped array geometry which gives the best 2-D angle estimation performances for the specified design parameters. The best geometry is determined by using Cramer-Rao Bound (CRB) and performance comparison is done with other planar array geometries.

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...
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...
Simulation of the in-plane structural behavior of unreinforced masonry walls and buildings using DEM
Pulatsu, Bora; Erdogmus, Ece; Lourenço, Paulo B.; Lemos, Jose V.; Tuncay, Kağan (2020-10-01)
In this study, a novel computational modeling strategy is proposed to estimate the lateral load capacity and behavior of unreinforced masonry (URM) structures. All commonly noted failure mechanisms are captured via the proposed modeling strategy using the discrete element method (DEM) in three-dimensions (3D). Masonry walls are represented as a system of elastic discrete blocks, where the nodal velocities are evaluated by integrating the equations of motion using the central difference method. Then, the mec...
Modeling of the Bosphorus exchange flow dynamics
SÖZER, ADİL; Ozsoy, Emin (2017-04-01)
The fundamental hydrodynamic behavior of the Bosphorus Strait is investigated through a numerical modeling study using alternative configurations of idealized or realistic geometry. Strait geometry and basin stratification conditions allow for hydraulic controls and are ideally suited to support the maximal-exchange regime, which determines the rate of exchange of waters originating from the adjacent Black and Mediterranean Seas for a given net transport. Steady-state hydraulic controls are demonstrated by ...
Design of attitude estimation algorithms for inertial sensors only measurement scenarios
Candan, Batu; Söken, Halil Ersin; Department of Aerospace Engineering (2022-3-24)
This thesis proposes four novel robust Kalman filter algorithms for attitude estimation using only the measurements of an inertial measurement unit. Efficiency and optimality of the Kalman filter based attitude filters are correlated with appropriate tuning of the covariance matrices. Manual tuning process is a difficult and time-consuming task. Specifically, the inertial measurement unit-only attitude estimation filters are prone to the external accelerations unless their covariances are adapted to gain ro...
