This study was carried out to derive and evaluate reference computed tomography (CT)-based indices for normal canine spine. CT and magnetic resonance images were acquired from 12 clinically normal Beagle dogs (normal group) and 50 dogs with 56 spinal disorders (patient group). Image acquisition regions were cervical spine (C2-T1), thoracic spine (T1-T13), and lumbar spine (L1-L7). Measured indi...

This paper presents an efficient FPGA-based architecture of CFAR target detector for radar system based on the automatic censored cell averaging (ACCA) detector based on ordered data variability (ODV). The ACCA–ODV detector estimates the unknown background level by dynamically selecting a suitable set of ranked cells and applying successive hypothesis tests. The proposed detector does not requi...

The presence of the sea clutter interfering signal sets limitations on the quality of radar detection in coastal and ocean environments. The CA-CFAR processor is the classic solution for detecting radar targets. It usually operates keeping constant its adjustment factor during the entire operation period. As a consequence, the scheme does not take into account the slow statistical variations of...

—The FFT lter bank-based summation CFAR detector is widely used for the detection of narrowband signals embedded in wideband noise. The simulation and implementation of this detector involves some problems concerning the reliable computation of the normalized detection threshold for a given probability of false alarm. This paper presents a comprehensive theoretical treatment of major aspects of...

CLUTTER DETECTION IN PULSE-DOPPLER RADAR SYSTEMS Ahmet Güngör M.S. in Electrical and Electronics Engineering Supervisor: Assist. Prof. Dr. Sinan Gezici August 2010 Among various types of radar systems, the pulse-Doppler radar is the most widely used one, especially in military applications. Pulse Doppler radars have a primary objective to detect and estimate the range and the radial velocity of...
