Space-Time Adaptive Processing Clutter Suppression Algorithm Based on Spatiotemporal Stationarity of Ionospheric Clutter in HFSWR

International Journal of Antennas and Propagation
In high-frequency surface wave radar (HFSWR) systems, ionospheric clutter is a common phenomenon that often causes targets to be submerged. Space-time adaptive processing (STAP) is a classical adaptive filtering algorithm.

Multi-Channel Synthetic Aperture Radar Imaging of Ground Moving Targets Using Compressive Sensing

IEEE Access, 2018
Integrated with the array technique, multi-channel processing can be applied to synthetic aperture radar of ground moving target imaging (SAR GMTIm), which is very powerful in remote sensing of smart city. To reduce the data sampling amounts, compressive

COMPRESSIVE SENSING SFGPR IMAGING ALGORITHM BASED ON SUBSPACE PROJECTION GROUND CLUTTER SUPPRESSION

Progress In Electromagnetics Research M, 2016
Stepped frequency ground penetrating radar (SFGPR) has received increasing attention in the field of ground penetrating radar technology due to its superiority in the detection performance. Compressed sensing (CS) SFGPR imaging reconstruction method can not merely reduce the measured imaging data volume, but also reconstruct target image with less ...

The Training Complex: Shattering of the Coniunctio, Boundary Violation, and Sibling Turbulence on the Horizontal Plane

Journal of Analytical Psychology, EarlyView.
Abstract This paper explores what is happening, for a trainee, when an ethical boundary violation occurs by the analyst with a fellow peer in training. I am approaching this through the Jungian concept of the alchemical vas as I attempt to make meaning of a catastrophic collapse of the analytic work.

Consistent Choice of Prey Source Habitat Across Diverse Landscapes by a Selective Insectivorous Bat

Integrative Zoology, EarlyView.
After analyzing the diet of the greater horseshoe bats in three distinct colonies, we identified significant spatial and temporal differences, particularly noting a stronger reliance on riparian habitats in Mediterranean areas. The species exhibits great ecological adaptability with strong plasticity in prey source habitats, shifting preferences among ...

Three-step ground moving target detection method for bistatic forward-looking SAR

The Journal of Engineering, 2019
Detecting ground moving target in bistatic forward-looking synthetic aperture radar (BFSAR) has become increasingly important in military and civil field. Compared with pulse Doppler radar, the long observation time and high resolution of BFSAR will lead

The Impact of Common Medications on Male Fertility: An Updated Systematic Review

Andrology, EarlyView.
ABSTRACT Background Compared with those of cytotoxic treatments, the potential effects of common medications on the fertility of men trying to conceive currently or planning to conceive in the future are less well described. The use of common medications may modify the gonadotropic axis, spermatogenesis, and epididymal maturation or alter male ...

Knowledge-aided Bayesian covariance matrix estimation in compound-Gaussian clutter [PDF]

, 2010
We address the problem of estimating a covariance matrix R using K samples zk whose covariance matrices are kR, where k are random variables. This problem naturally arises in radar applications in the case of compound-Gaussian clutter. In contrast to the

From barriers to benefits: A personalized sleep intervention enhances sleep duration and emotional health in chronic short sleepers

British Journal of Psychology, EarlyView.
Abstract This pilot study evaluated a personalized sleep intervention incorporating motivational interviewing techniques to address sleep barriers, along with tailored sleep hygiene and extension for chronic short sleepers. Eleven university students completed a 14‐day sequential intervention (baseline, sleep hygiene and a combined phase adding 90‐min ...
