Decomposition method for complex target RCS measuring

2017-11-09 · IEEE First Ukraine Conference on Electrical and Computer Engineering (UKRCON) 2017 11 · Alexander Maslovskiy Department of Theoretical Radiophysics, Ukraine Nikolay Kolchigin Department of Theoretical Radiophysics, Ukraine Maxim Legenkiy Department of Theoretical Radiophysics, Ukraine Mariya Antyufeyeva Department of Theoretical Radiophysics, V.N.Karazin Kharkiv National University, Kharkiv, Ukraine

In this paper a method of monostatic RCS measuring in real conditions for complex shaped objects is proposed. The basic idea of the method is to provide measuring in near field zone for different parts of the object (fragments) separately. This technique is titled "decomposition method". After such measurements all RCS data are summed and one can obtain the average RCS of investigated object. Such method is much more accessible in comparison with natural measurements in far field zone. In this paper the decomposition method is tested numerically. For this a model of complex shape object (tank T-90) is divided into the fragments for some direction of view. It is shown that the sum of RCS of the fragments is close to the full object RCS for corresponding direction.

On the measure of conflicts: A MUS-Decomposition Based Framework

2014-06-01 · Said Jabbour, Yue Ma, Badran Raddaoui, Lakhdar Sais 외

Measuring inconsistency is viewed as an important issue related to handling inconsistencies. Good measures are supposed to satisfy a set of rational properties. However, defining sound properties is sometimes problematic…

Image decomposition plays a crucial role in various computer vision tasks, enabling the analysis and manipulation of visual content at a fundamental level. Overlapping images, which occur when multiple objects or scenes …

Revisiting text decomposition methods for NLI-based factuality scoring of summaries

2022-11-30 · John Glover, Federico Fancellu, Vasudevan Jagannathan, Matthew R. Gormley 외

Scoring the factuality of a generated summary involves measuring the degree to which a target text contains factual information using the input document as support. Given the similarities in the problem formulation, prev…
