Research on Polarization Cancellation of Nonstationary Ionosphere Clutter in HF Radar System
International Journal of Antennas and Propagation, 2015 Oblique projection polarization filter (OPPF) can be applied as an effective approach for interference cancellation in high-frequency surface wave radar (HFSWR) and other systems. In order to suppress the nonstationary ionosphere clutter further, a novel

EFFECT OF NON GAUSSIAN WEATHER CLUTTER ON PERFORMANCE OF CLUTTER-SUPPRESSION FILTERS
International Conference on Aerospace Sciences and Aviation Technology, 1985 In this paper it is investigated the performance of clutter suppression filters in non Gaussian clutter. The model chosen is Log-normal clutter and the filters considered are the optimum MTI filter and the linear prediction error filter. The performance of both types of filters in Gaussian clutter as expressed by the improvement factor (I.F) is ...

Algebraic spectral moments based moving clutter parameter estimation and clutter suppression
, 2014 In many modern radar systems, it is desired to detect the presence of targets in the interference which includes clutter and noise. Various signal processing techniques are proposed to effectively suppress the clutter and increase the signal to ...

Remote Sensing in Ecology and Conservation, EarlyView.We developed PZM‐YOLO to automatically detect plateau zokor mounds in UAV imagery of alpine meadows. The model achieved reliable detection of small and densely distributed mounds under complex backgrounds, outperforming the baseline YOLOv5s. This framework supports mound counting, mound position, rodent impact assessment, and grassland restoration ...

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.

Safety Science and Technology, EarlyView.We present an AI‐assisted ground‐penetrating radar framework to noninvasively detect and quantify smoldering wildfire‐induced subsurface cavities in peatlands. A ResNet model accurately predicts cavity geometry from GPR images, enabling improved assessment of underground fire damage and hazards.

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 ...

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.
