Enhanced Pre-STAP Beamforming for Range Ambiguous Clutter Separation with Vertical FDA Radar
Medium pulse repetition frequency (MPRF) is an important mode in airborne radar system. Since MPRF mode brings both Doppler and range ambiguities, it causes difficulty for the airborne radar to suppress ground or sea clutter. In recent years, it has been

Vertical Air Motion Retrievals From Airborne
In-cloud vertical air motion is a key parameter to describe cloud dynamics and lifecycles. Short-wavelength ($Ka$- and $W$-band) radars are often used to observe clouds and extract the vertical air motion from the radar-measured Doppler velocity. However,

Machine‐Learning Microfluidic Minute‐Scale Microorganism Metrics Monitoring(M6)
ABSTRACT On‐site monitoring of microorganisms remains challenging because of low concentrations, strong background interference, and dynamic aerosol diffusion, particularly for aerosol‐transmitted pathogens. Here, we report a rapid detection platform that integrates a Puri‐focusing microfluidic chip, electrochemical impedance spectroscopy (EIS), and ...

Medicane characteristics from high‐resolution satellite radar observations
This study uses high‐resolution observations from satellite synthetic aperture radar (SAR) to reveal that medicanes, cyclones with tropical features in the Mediterranean basin, have dynamical characteristics with attributes comparable with those of tropical cyclones of similar intensities, but smaller outer sizes and Rossby numbers.
