Non-parametric radar detection in homogeneous and non-homogeneous environments

In this study, non-parametric constant false alarm rate (CFAR) radar processors are investigated. Performance analysis of the system, which uses generalized sign test in its detector, is done in homogeneous and non-homogeneous environments. Also the performance of the system is compared with the performance of the cell averaging constant false alarm rate (CA-CFAR) detector in the homogeneous and non-homogeneous environments.


Improvement of radar detection by doppler pattern matching
Çelebi, Duygu; Severcan, Mete; Department of Electrical and Electronics Engineering (2006)
In this thesis, improvement of Cell Averaging Constant False Alarm Rate (CA CFAR) radar processors is studied. A new improvement method is proposed that will reduce probability of false alarm while keeping probability of detection at good values. This method makes use of Doppler spreading patterns that appear after Doppler processing. Therefore this method is called Doppler Pattern Matching (DPM). Performance of the algorithm has been investigated by Monte Carlo simulations. In order to evaluate the perform...
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...
Examination of Target RCS Characteristics in FDA Radars
Cetintepe, Cagri; Demir, Şimşek (2014-07-11)
This paper reports on the preliminary analysis of frequency diverse array (FDA) radars for simple target geometries. The radar system employs an FDA and a isotropic element as the transmitter and receiver antennas, respectively, and illuminates a target consisting of an arbitrary arrangement of ideal point scatterers. After establishing a signal model for the voltage waveform received by this radar system, the study then considers particular target arrangements and compares the average received power to tha...
Probabilistic distance clustering on networks
İyigün, Cem (null; 2018-11-05)
In this study, a soft clustering problem on networks is investigated. It is assumed that cluster centers are located not only on vertices, but also on the edges of the network. Two different soft assignment schemes are studied where different membership functions are considered for the assignments. Structural properties for the clustering problem have been derived for different problem settings and the relation to the p-median problem has been shown under specific conditions. As a solution approach, a metah...
Radar performance analysis approaches for the evaluation of radar systems
Yener, Ümit; Kuzuoğlu, Mustafa; Department of Electrical and Electronics Engineering (2018)
In this thesis study, some approaches are proposed for radar performance analysis. It turns out that average power and antenna aperture area (equivalently, antenna gain) are the most important parameters for the assessment or comparison of radar systems. Search and track load concepts and the utilization trade between search and tracking tasks in multifunction radars are also presented. For long distance search / tracking tasks, performance of a two-radar system is analyzed, and it is shown that cross range...
