High-speed target detection algorithm based on the RFT for SABBEWR
The Journal of Engineering, 2019 In space-air-based bistatic early warning radar (SABBEWR) application, the standard Radon–Fourier transform (RFT) can effectively reduce the deterioration of target-detection performance caused by the serious range migration.

A reweighted matrix completion algorithm for sparse inverse synthetic aperture radar imaging
IET Radar, Sonar & Navigation, 2023 Sparse inverse synthetic aperture radar (ISAR) imaging can be generally achieved by compressed sensing (CS) methods because sparse sampling disables the approach of conventional range Doppler. However, the CS‐based methods have to convert the matrix into

Spectral De-Aliasing Method of Micro-Motion Signals Based on a Complex-Valued U-Net Network
Remote Sensing, 2023 Spectrum aliasing occurs in signal echoes when the sampling frequency does not comply with the Nyquist Sampling Theorem. In this scenario, the extraction of micro-motion parameters becomes challenging.

Probabilistic early warning signals [PDF]
Ecology and Evolution, 2021 Abstract Ecological communities and other complex systems can undergo abrupt and long‐lasting reorganization, a regime shift, when deterministic or stochastic factors bring them to the vicinity of a tipping point between alternative states. Such changes can be large and often arise unexpectedly.

ISAR High-Resolution Imaging Method With Joint FISTA and VGGNet
IEEE Access, 2021 With regard to inverse synthetic aperture radar (ISAR) imaging, traditional range-Doppler (RD) algorithm is inapplicable to sparse aperture. Although compressive sensing (CS) algorithm can overcome this problem, the imaging resolution is not high enough.

Meteorological clutter suppression method for ball-borne radar based on Kalmus filter
The Journal of Engineering, 2019 Aimed at the problem that the unmanned aerial vehicle (UAV) target is difficult to be detected in the meteorological clutter because of their close velocity, a new detection method is proposed for the ball-borne radar based on Kalmus filter. Firstly, the
