Directive Antenna Clutter Loss in Slant Paths
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT This paper investigates the development of a clutter loss model specifically for slant paths involving directive antennas. Conventionally, clutter loss is characterized by using isotropic antennas to facilitate standard link budget calculations via single antenna gain values.

On the RFI Detection in Differential Interferometric Synthetic Aperture Radar [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information SciencesSynthetic Aperture Radar (SAR) can image the ground with a wide area and high resolution at all times and in all weather and has become an important means of remote sensing.

The Newest Federalism and Population Health
The Milbank Quarterly, EarlyView.Policy Points In the United States, social policies at the federal, state, and local levels affect population health. The country is undergoing major changes in its social policies and intergovernmental relations. As both state and local governments have taken different approaches to social policies, where one resides and the socioeconomic resources ...

Dextractor:Deformation Extractor Framework for Monitoring-Based Ground Radar
Remote SensingThe radio frequency (RF) data generated from a single-chip millimeter-wave (mmWave) ground-based multi-input multi-output (GB-MIMO) radar can provide a highly robust, precise measurement for deformation in harsh environments, overcoming challenges such ...

Legitimacy and Persuasion in the Anglo‐Scottish Wars of the 1540s
History, EarlyView.Abstract The considerable efforts of the invading English to justify their activities and garner support during the Anglo‐Scottish wars of the 1540s are well known. Recent welcome attention to Scottish texts produced during the conflict has begun to correct a previous historiographical imbalance towards English materials.

IEICE Transactions on Communications, 2009 The purpose of this study is the real-time estimation of Doppler spectral moments for precipitation in the presence of ground clutter overlap. The proposed method is a frequency domain approach that uses a Gaussian model both to remove clutter spectrum and to estimate weather spectrum. The main advantage of this method is that it does not use processes

Analysis of the behaviour of ground clutter on behalf of clutter suppression with solidar
, 1991 Interest in clutter is almost universal in radar research, because most of the radar echo signals received by radar do not originate only from the desired target, but also from surrounding objects or surfaces which tend to mask the target signal.

The social life of money for children
The British Journal of Sociology, EarlyView.Abstract Inspired by Nigel Dodd's The Social Life of Money, this article proposes an analysis of entangled economic lives, that is, how meaning, structures and politics jointly shape the flow of monies within households. The past decades have marked a shift from “childrearing expenditures” to “parenting investments” that align with new visions of both ...
