Target detection is one of the important applications in the field of remote sensing. The Gaofen-3 (GF-3) Synthetic Aperture Radar (SAR) satellite launched by China is a powerful tool for maritime monitoring. This work aims at detecting ships in GF-3 SAR images using a new land masking strategy, the appropriate model for sea clutter and a neural network as the discrimination scheme. Firstly, th...

Effects of parenterally administered pharmacologic doses of glucagon on canine hindlimb blood flow were studied. Cardiac output (CO), mean arterial pressure (MAP), total peripheral resistance (TPR), common femoral artery flow (CFAQ), common femoral artery resistance (CFAR), percentage shunt in the hindlimb (AVA%) determined by 99mTc microsphere technique, the volume of hindlimb shunt flow (AVAQ...

A new parallel algorithm for signal processing and a parallel systolic architecture of a CFAR processor with adaptive censoring and post detection integration (API) are presented in the paper. The processor proposed is used for target detection when echoes from targets are performed in conditions of binomial distribution pulse jamming. The property of the algorithm proposed is its ability autom...

The design and field programmable gate array (FPGA)-based realisation of automatic censored cell averaging (ACCA) constant false alarm rate (CFAR) detector based on ordered data variability (ODV) is discussed here. The ACCA–ODV CFAR algorithm has been recently proposed in the literature for detecting radar target in non-homogeneous background environments. The ACCA–ODV detector estimates the un...

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...
