Improved Dimension-Reduced Structures of 3D-STAP on Nonstationary Clutter Suppression for Space-Based Early Warning Radar

Remote Sensing, 2022
By introducing degrees of freedom (DOFs) in elevation, the elevation-azimuth-Doppler three-dimensional space–time adaptive processing (3D-STAP) methods have better performance when suppressing the nonstationary clutter caused by the Earth’s rotation in ...

Beamforming issues in modern MIMO Radars with Doppler [PDF]

, 2006
In traditional beamforming radar systems, the transmitting antennas send coherent waveforms which form a highly focused beam. In the MIMO radar system, the transmitter sends noncoherent (possibly orthogonal) broad (possibly omni-directional) waveforms ...

How Program‐ and Community‐Led Design Settings Affect Resilience Approaches to Sustainable Development Projects

Sustainable Development, EarlyView.
ABSTRACT Sustainable Development interventions must deal with rapid and novel changes affecting complex social‐ecological systems, calling for design based on a resilience approach. However, limited analytical attention has been paid to the design settings in which such approaches are deployed.

Robust knowledge-aided sparse recovery STAP method for non-homogeneity clutter suppression

The Journal of Engineering, 2019
Conventional space–time adaptive processing (STAP) methods would suffer severely performance loss in the complex clutter environment of an airborne-phased array radar, especially when the estimated clutter covariance matrix (CCM) is corrupted by the ...

A new multipath mitigation method for GNSS receivers based on antenna array [PDF]

, 2012
the potential of small antenna array for multipath mitigation in GNSS systems is considered in this paper. To discriminate the different incoming signals (Line of sight and multipaths), a new implementation of the well known SAGE algorithm is proposed ...

Using multilayer socioecological networks to assess ecosystem service flow in a subsistence farming community in Papua New Guinea

People and Nature, Volume 8, Issue 4, Page 854-870, April 2026.
Abstract Ecosystem services are rapidly degrading under anthropogenic pressure. Therefore, it is increasingly important to understand how ecosystem services flow, particularly at local scales, where people directly rely on nature for their livelihoods and well‐being. Many ecosystem services are underpinned by ecological (e.g.

An Overview on Sparse Recovery-based STAP

Leida xuebao, 2014
This paper gives a brief review on the Sparse-Recovery (SR)-based Space-Time Adaptive Processing (STAP) technique. First, the motivation for introducing sparse recovery into STAP is presented.
