Radon-Fourier transform (RFT) is an optimal method for rectilinearly moving targets to overcome range migration with good coherent integration performance in radars. However, it is computationally burdensome because it jointly searches over the range and velocity domains. In this letter, a novel efficient range migration compensation method is proposed. In this algorithm, residual velocity is searched instead of whole velocity range and then a novel low-complexity Doppler ambiguity compensation procedure is executed to search for Doppler ambiguity factor. Compared to the RFT method, the proposed method can achieve a similar detection performance with lower computational cost. Simulation results are provided to verify the effectiveness of the proposed algorithm.

Low Complexity Keystone Transform and Radon Fourier Transform Utilizing Chirp-Z Transform Culha, Onur; Tanık, Yalçın (2020-01-01) Keystone Transform (KT) and Radon Fourier Transform (RFT) are two popular methods proposed to overcome range migration in radars. A major concern in these methods is the computational complexity for real time operations. In this paper, a low complexity implementation of recurrent chirp-z transform (CZT) is offered in order to be employed in fast KT with no loss in performance. Additionally, a novel RFT implementation utilizing recurrent CZT is proposed to take advantage of the fast execution of repeated CZT...
A particle swarm optimization approach for hexahedral mesh smoothing Yilmaz, A. Egemen; Kuzuoğlu, Mustafa (Wiley, 2009-05-10) There are some approaches for all-hexahedral mesh quality improvement by means of node-movement while preserving the connectivity. Among these methods, the most easily implemented and well known one is the Laplacian smoothing method; however, for this method mesh quality improvement is not guaranteed in all cases, and this approach might cause inverted elements especially in concave regions. In this work, a method for the improvement of hexahedral mesh shape-quality Without causing inverted elements is prop...
A CIRCLE DETECTION APPROACH BASED ON RADON TRANSFORM Okman, O. Erman; Akar, Gözde (2013-05-31) In this paper a novel fast circle detection algorithm is proposed which depends on the spatial properties of the connected components on the image. Two 1-D transforms of each connected component is obtained by taking the Radon Transform of the image for two different directions, which are in fact the integrations of the image through horizontal and vertical directions. Circles are detected using the similarities of detected peaks on the transformed functions and the characteristics of the values in between ...
Efficient and broadband guided wave one-way mode-order conversion with theoretical and numerical analysis Ustun, Kadir; KURT, HAMZA (2013-11-01) In this article, an efficient method of asymmetric conversion of guided modes is investigated. From a basic excitation consisting of (mainly) the lowest-order mode of the input multimode strip waveguide, we achieve a conversion efficiency of similar to 60% on average, in the forward propagation case, while the backward propagation is suppressed below 10%. The analytical formulation is based on electromagnetic wave theory with orthogonality relations. Affirmative results between the theoretical and numerical...
Süperpikseller ve İmza Tabanlı Yöntemler Kullanarak Hiperspektral Hedef Tespiti Kütük, Mustafa; Alatan, Abdullah Aydın (2019-06-27) Spectral signature based methods which form the mainstream in hyperspectral target detection can be classified mainly in three categories as the methods using background modeling, subspace projection based methods, and hybrid methods merging linear unmixing with background estimation. A common characteristic of all these methods is to classify each pixel of the hyperspectral image as a target or background while ignoring the spatial relations between neighbor pixels. Integration of contextual information de...
