Moving Targets: Recognition of Alkyl Groups
Chemistry – A European Journal, 2006AbstractAlkyl chains can adopt seemingly unusual conformations, such as helices, when bound to natural and synthetic hydrophobic receptors. This plasticity allows the alkanes to assume shapes that are congruent to the receptor's space and fill that space properly.

Evaluation of target segmentation on SAR target recognition
2017 4th International Conference on Information, Cybernetics and Computational Social Systems (ICCSS), 2017Target segmentation of synthetic aperture radar (SAR) images is one of the challenging problems in SAR image interpretation, which often serves as a processing step for SAR target recognition. Target segmentation tries to separate the target from the background thus eliminating the interference of background noises or clutters.

Gated viewing for target detection and target recognition
SPIE Proceedings, 1999Gated viewing using short pulse lasers and fast cameras offers many new possibilities in imaging compared with passive EO imaging. Among these we note ranging capability, large target-to-background contrast also in low visibility, good penetration capability trough obscurants and vegetation as well as through shadows in buildings, cars, etc.

Radioligand Recognition of Insecticide Targets
Journal of Agricultural and Food Chemistry, 2018Insecticide radioligands allow the direct recognition and analysis of the targets and mechanisms of toxic action critical to effective and safe pest control. These radioligands are either the insecticides themselves or analogs that bind at the same or coupled sites.

Target recognition in acoustics
The Journal of the Acoustical Society of America, 1988The classification/identification of underwater stationary objects can be acoustically achieved by means of passive or active sonar. Moving targets are the “easy case,” since they can be identified by their Doppler factor, and will not be discussed here.

Automatic target recognition of ground targets
2013An overview of the fundamentals of ground target recognition using SAR has been given. There is a tendency, when discussing ground target ATR, to consider only the most complex problems consisting of very many target classes and challenging clutter environments.

A sonar target recognition experiment
The Journal of the Acoustical Society of America, 1979This paper presents results of an experiment to determine the feasibility of an active sonar target recognition system. Echo data were obtained from 16 targets of maximum dimension 12 in., submerged in a salt water pool. The target frequency responses in the 15–45-kHz band were used to characterize the targets. The information in the frequency response

Unification of Automatic Target Tracking and Automatic Target Recognition
SPIE Proceedings, 2014The subject being addressed is how an automatic target tracker (ATT) and an automatic target recognizer (ATR) can be fused together so tightly and so well that their distinctiveness becomes lost in the merger. This has historically not been the case outside of biology and a few academic papers.

A quick target recognition technology
Proceedings of 2011 International Conference on Electronic & Mechanical Engineering and Information Technology, 2011Target recognition technology has been widely used in different areas around the world. Especially, target recognition technology developed for platforms such as satellite, unmanned reconnaissance plane, aircraft, etc. has been the focus of attention for various countries.

Within this chapter the various processes which are required to provide a radar target recognition function are brought together and build on the concepts that have been discussed earlier in the book. Key radar measurements issues, which were extensively presented earlier, are reviewed and include a discussion on target signature distortion in Section ...
