In this work, a new algorithm for multiple emitter direction finding by using a single antenna moving along a circular trajectory is proposed. The problem is formulated by taking the Doppler frequency shift, caused by the movement of the antenna. into account, and by assuming that the information, hidden in the incoming signals, does not change in the observation duration. The proposed direction finding algorithm is, therefore, based on single snapshot processing and also on the linear prediction method developed in [1,2]. It has no restriction on the correlation of the incoming signals since it performs a single snapshot processing. The algorithm performance is investigated through computer simulations and it is observed that the root-mean-square errors of the direction of arrival estimates are less than one degree in most cases. Therefore, it seems reasonable to use the proposed direction finding algorithm in some particular applications, for instance, in identifying the environment for calibration purposes.

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 ...
Distance Measurement by Phase Tracking Dogan, Ozan; Demir, Ibrahim; Aydin, Umut (2017-05-18) In this work, multi frequency continuous wave radar phase unwrapping and the target tracking algorithm are combined. In order to unwrap the wrapped measurement, the unwrapped range measurement or the predicted range is utilized. Methods are assessed with the simulations and field tests. Final tracked range accuracy is shown to be increased without an additional phase unwrapping procedure.
Broadband solutions of potential integral equations with NSPWMLFMA Khalichi, Bahram; Ergül, Özgür Salih; Ertürk, Vakur B. (Institute of Electrical and Electronics Engineers (IEEE), 2019-06) In this communication, a mixed-form multilevel fast multipole algorithm (MLFMA) is combined with the recently introduced potential integral equations (PIEs), also called as the A-phi system, to obtain an efficient and accurate broadband solver that can be used for the solution of electromagnetic scattering from perfectly conducting surfaces over a wide frequency range including low frequencies. The mixed-form MLFMA uses the nondirective stable planewave MLFMA (NSPWMLFMA) at low frequencies and the conventio...
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...
Measurement reduction for mutual coupling calibration in DOA estimation Aksoy, Taylan; Tuncer, Temel Engin (2012-05-17) Mutual coupling is an important source of error in antenna arrays that should be compensated for super resolution direction-of-arrival (DOA) algorithms, such as Multiple Signal Classification (MUSIC) algorithm. A crucial step in array calibration is the determination of the mutual coupling coefficients for the antenna array. In this paper, a system theoretic approach is presented for the mutual coupling characterization of antenna arrays. The comprehension and implementation of this approach is simple leadi...
