Efficient Range Migration Compensation Method Based on Doppler Ambiguity Shift Transform Culha, Onur; Tanık, Yalçın (2022-03-01) 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 joi...
Turbo Parametric Spectral Estimation Method of Clutter Profile for Adaptive Radar Detection Eraslan, Berna; Güvensen, Gökhan Muzaffer; Tanık, Yalçın (2020-06-01) © 2020 IEEE.Identification of unwanted components of a received echo is critical to improving the radar detection performance. Previously proposed parametric parameter estimation methods, such as MUSIC, ESPRIT, and Burg we...
A Novel Neural Network Architecture for Radar Clutter Classification Eraslan, Berna; Güvensen, Gökhan Muzaffer; Tanık, Yalçın (2020-01-01) In recent years, potential capabilities of modern radars have become tremendous, with rapid advances in electronics and software technologies. If the radar system processes received echoes based on clutter characteristics,...
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. I...
Expectation Maximization-Based Detection in Range-Heterogeneous Weibull Clutter Doyuran, Ulku Cilek; Tanık, Yalçın (2014-10-01) The problem of radar target detection in Weibull and range-heterogeneous clutter is considered. The clutter component in each range cell is modeled as an instance of a random variable belonging to one of several Weibull di...
Experimental Evaluation of the Knowledge-Aided Sigma-Delta STAP Algorithm to Improve GMTI Performance Anadol, Erman; Tanık, Yalçın (2014-06-05) A novel knowledge-aided processing scheme is proposed for use in Ground Moving Target Indication (GMTI) operation to be operated in real time on airborne SAR/GMTI sensors. The proposed approach is based on the Sigma-Delta ...
A Reduced-State Ungerboeck Type MAP Receiver with Bidirectional Decision Feedback for M-ary Quasi Orthogonal Signaling Güvensen, Gökhan Muzaffer; Tanık, Yalçın; Yılmaz, Ali Özgür (2014-02-01) In this paper, we propose a generic receiver based on optimum maximum likelihood sequence estimation (MLSE) employing a generalized Ungerboeck metric with significantly reduced complexity for the general class of M-ary qua...
