Atomic Decomposition for ISAR Imaging

2006 IEEE Conference on Radar, 2006
We explore the capabilities of atomic decomposition (AD) for ISAR imaging. On the contrary to our previous work with AD where our research was focused on radar signal detection and maximization of sensitivity, the main concern in ISAR imaging based on AD is to obtain focused images, target feature extraction and low computational burden.

NLI under the Microscope: What Atomic Hypothesis Decomposition Reveals

North American Chapter of the Association for Computational Linguistics
Decomposition of text into atomic propositions is a flexible framework allowing for the closer inspection of input and output text. We use atomic decomposition of hypotheses in two natural language reasoning tasks, traditional NLI and defeasible NLI, to ...

Atomic decomposition-based SAR imaging

IET International Radar Conference 2013, 2013
Conventional SAR image formation algorithms are based on data collection geometries. We propose a model-based SAR image formation scheme in this paper. Compared with conventional geometry-based SAR imaging algorithms, model-based imaging technique is independent of specific geometry, and focuses the backscattered echoes progressively by estimating ...

Atomic decomposition for radar applications

IEEE Transactions on Aerospace and Electronic Systems, 2008
In this paper, we explore the promising capabilities of atomic decomposition (AD) for radar-related applications from a practical point of view. Some enhancements and new approaches are proposed herein, and their implementations are fully detailed. We apply the AD algorithms in two different environments, for signal detection where high sensitivity is ...

Atomic decomposition of vector measures

Siberian Mathematical Journal, 1990
Let F be a K-space [cf. \textit{L. V. Kantorovich, B. Z. Vulikh} and \textit{A. G. Pinsker}, Usp. Mat. Nauk 6, Nr. 3(43), 31-98 (1951; Zbl 0043.332); English translation in Amer. Math. Soc., Transl., II. Ser. 27, 51-124 (1963; Zbl 0125.341)]. The paper deals with an atomic structure of the set F-bva(\({\mathcal A},Y)\) of measures (finitely additive ...

The roaming atom pathway in formaldehyde decomposition

The Journal of Chemical Physics, 2006
We present a detailed experimental and theoretical investigation of formaldehyde photodissociation to H2 and CO following excitation to the 2141 and 2143 transitions in S1. The CO velocity distributions were obtained using dc slice imaging of single CO rotational states (v=0, jCO=5–45).

Atomic decomposition with evolutionary pursuit

Digital Signal Processing, 2003
Abstract An atomic decomposition of a signal is an expression of the signal as a superposition of a parametric collection of waveforms. Basis expansions, especially orthogonal cases such as Fourier and wavelet bases, are the most commonly used atomic models.

Atomic decomposition-based SAR imaging technique

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
The conventional SAR imaging algorithms are developed based on specified imaging geometry models, and these algorithms become more complex considering finer resolution or more complicated geometry. The quality of the product is measured by resolution, PSLR and ISLR, etc. without regard to its application.
