Enhanced Pre-STAP Beamforming for Range Ambiguous Clutter Separation with Vertical FDA Radar

open access: yesRemote Sensing, 2021
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 $W$-Band Cloud Radar

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
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,

Polarisation-space-time adaptive processing for heterogeneous clutter suppression of airborne-phased array radar

open access: yesThe Journal of Engineering, 2019
Conventional space-time adaptive processing (STAP) achieves clutter suppression by combining spatial signals and the temporal pulses. However, extreme slow-moving target cannot be effectively detected by space-time joint filtering in ambiguous and non ...

A Multiple Interference Suppression Algorithm Based on Airborne Bistatic Polarization Radar

open access: yesLeida xuebao, 2022
To solve the problem of the simultaneous suppression of main-lobe and side-lobe interferences, this study applies polarization information as input to the airborne bistatic radar and constructs an airborne bistatic polarization-sensitive array.

Machine‐Learning Microfluidic Minute‐Scale Microorganism Metrics Monitoring(M6)

open access: yesAdvanced Science, EarlyView.
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

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
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.
