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 distributions. We use the expectation-maximization algorithm to estimate parameters of the distribution and set the threshold accordingly. The performance of the proposed receiver is investigated through computer simulations and observed to be superior compared with numerous well-known methods.

Region Based Target Detection Approach for Synthetic Aperture Radar Images and Its Parallel Implementation
Nar, Fatih; Demirkesen, Can; Okman, O. Erman; ÇETİN, MÜJDAT (2012-04-26)
Automatic target detection (ATD) methods for synthetic aperture radar (SAR) imagery are sensitive to image resolution, target size, clutter complexity, and speckle noise level. However, a robust ATD method needs to be less sensitive to the above factors. In this study, a constant false alarm rate (CFAR) based method is proposed which can perform target detection independent of image resolution and target size even in heterogeneous background clutter. The proposed method is computationally efficient since cl...
Automatic small target detection in synthetic infrared images
YARDIMCI, Ozan; Ulusoy, İlkay (2017-04-11)
Automatic detection of targets from far distances is a very challenging problem. Background clutter and small target size are the main difficulties which should be solved while reaching a high detection performance as well as a low computational load. The pre-processing, detection and post-processing approaches are very effective on the final results. In this study, first of all, various methods in the literature were evaluated separately for each of these stages using the simulated test scenarios. Then, a ...
Effective training set sampling strategy for SVDD anomaly detection in hyperspectral imagery
Ergul, Mustafa; Sen, Nigar; Okman, O. Erman (2014-05-07)
Anomaly detection (AD) is an important application for target detection in remotely sensed hyperspectral data. Therefore, variety kinds of methods with different advantages and drawbacks have been proposed for past two decades. Recently, the kernelized support vector data description (SVDD) based anomaly detection approaches has become popular as these methods avoid prior assumptions about the distribution of data and provides better generalization to characterize the background. The global SVDD needs a tra...
Automatic small target detection in infrared images of various backgrounds from various distances
Yardımcı, Ozan; Ulusoy, İlkay; Department of Electrical and Electronics Engineering (2015)
Automatic detection of small targets in various backgrounds from far distances is a very challenging problem. Background clutter and small target size are the main difficulties which should be solved while reaching a very high detection performance as well as a very low computational load. In this thesis, various methods such as Top-Hat and Wavelet Transform, edge, filtering, saliency and feature based algorithms are investigated. All of the methods are compared using some realistic test scenarios, which ar...
Radar target detection in non-gaussian clutter
Doyuran, Ülkü; Tanık, Yalçın; Department of Electrical and Electronics Engineering (2007)
In this study, novel methods for high-resolution radar target detection in non-Gaussian clutter environment are proposed. In solution of the problem, two approaches are used: Non-coherent detection that operates on the envelope-detected signal for thresholding and coherent detection that performs clutter suppression, Doppler processing and thresholding at the same time. The proposed non-coherent detectors, which are designed to operate in non-Gaussian and range-heterogeneous clutter, yield higher performanc...
