Brightness temperature of extended targets
ICMMT'98. 1998 International Conference on Microwave and Millimeter Wave Technology. Proceedings (Cat. No.98EX106), 2002A method of establishing formulas for calculating brightness temperature of extended targets at microwave frequency is introduced in this paper. The formulas are obtained through the statistical process of a large amount of measured data. The formulas for concrete road, asphalt road, and crushed stone are presented, which are established by this method.

Observation of extended targets with antenna arrays
IEEE Transactions on Aerospace and Electronic Systems, 2000Moments of the scattering function are a superb set of parameters representing an extended radar target. This set perfectly matches the adopted radar observation sequence (detection, position estimation, resolution, recognition and tracking). The problem of the moment estimation in radar systems with antenna arrays is considered.

Extended target-site specificity for a hammerhead ribozyme
Gene, 1992In vitro mutagenesis has been used to systematically mutate the GUC target site cleaved by a synthetic ribozyme based on the catalytic domain of the satellite RNA of tobacco ringspot virus. Amongst the spectrum of changes, it is found that GUC, UUC, CUC, GUA and GUU targets show equivalent rates of cleavage.

Extended Functions of Multiple Instances for target characterization
2014 6th Workshop on Hyperspectral Image and Signal Processing: Evolution in Remote Sensing (WHISPERS), 2014An extension of the Function of Multiple Instances (FUMI) algorithm for target characterization is presented. FUMI is a generalization of Multiple Instance Learning (MIL). However, FUMI differs significantly from standard MIL and supervised learning approaches because only data points which are functions of class concepts are available.

The processing of target resolving for radar extended target detection
IEEE International Conference on Robotics, Intelligent Systems and Signal Processing, 2003. Proceedings. 2003, 2004Based on the target plots data acquired from detection of the antiship guidance radar receiver, the phenomenon of extended target split caused by the radar high resolution characteristic is discussed. The repeated detection phenomenon of target and its influences brought by the feature of radar antenna scanning mode are described.

Extending Executability of Applications on Varied Target Platforms
2011 IEEE International Conference on High Performance Computing and Communications, 2011High-performance applications are often developed for a specific class of target platforms and executing them on the increasing variety of Cloud and grid environments requires substantial adjustments and reconciliation. The aim of our framework, called ADAPT (Adaptive Application and Platform Translation), is to allow adaptation of applications for ...

Saccades to spatially extended targets: the role of eccentricity
NeuroReport, 2004Size and eccentricity of visual targets are known to modulate saccade parameters. Here we asked for a possible interaction between these target properties. We investigated latency and amplitude of saccades to targets of varying diameter presented at various eccentricities in the visual field.

A Super-Resolution Algorithm for Extended Target Localization
2019 IEEE 8th International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP), 2019We aim to localize extended targets (i.e. non-point targets) using stepped-frequency (SF) radar measurements from multiple transceivers. In particular, we consider a general signal model with directionally varying target reflectivity that can account for many types of extended target geometries. We localize targets under this signal model using a novel
