Fast Variational Bayesian Inference for Space-Time Adaptive Processing

open access: yesRemote Sensing, 2023
Space-time adaptive processing (STAP) approaches based on sparse Bayesian learning (SBL) have attracted much attention for the benefit of reducing the training samples requirement and accurately recovering sparse signals. However, it has the problem of a

Robust Space Time Adaptive Processing Methods for Synthetic Aperture Radar

open access: yesApplied Sciences, 2020
This paper proposes two modified space time adaptive processing (STAP) methods based on piecewise sub-apertures and data constraints for non-stationary interference cancellation in synthetic aperture radar (SAR) applications. In these methods, the entire

MIMO radar space–time adaptive processing using prolate spheroidal wave functions [PDF]

open access: yes, 2008
In the traditional transmitting beamforming radar system, the transmitting antennas send coherent waveforms which form a highly focused beam. In the multiple-input multiple-output (MIMO) radar system, the transmitter sends noncoherent (possibly ...

Frequency Diverse Array SAR With Fast-Time Space-Time Adaptive Processing for Subsurface Imaging

open access: yesIEEE Access, 2023
Different from the ground penetration radar providing only one-dimensional image, synthetic aperture radar (SAR) can produce two-dimensional and even three-dimensional image, which is meaningful in subsurface imaging, but possible layover effects may be ...

A Single-Dataset-Based Pre-Processing Joint Domain Localized Algorithm for Clutter-Suppression in Shipborne High-Frequency Surface-Wave Radar

open access: yesSensors, 2020
Due to the motion of the platform, the spectrum of first-order sea clutter will widen and mask low-velocity targets such as ships in shipborne high-frequency surface-wave radar (HFSWR).
