Cognitive Space-time Adaptive Processing Technology for Airborne Radar in Complex Environments

Leida xuebao
China has one of the longest land borders in the world and features a diverse range of terrain types and a dense electromagnetic environment. Therefore, in practical applications, airborne radar faces complex environments.

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

Sustainable Development, Volume 34, Issue 6, Page 8789-8804, October 2026.
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.

Phase-Only Space-Time Adaptive Processing [PDF]

, 2021
Space-time adaptive processing (STAP) is a well-known and effective method to detect targets, obscured by interference, from airborne radars that works by coherently combining signals from a phased antenna array (spatial domain) with multiple radar ...

Sea Clutter Suppression for Shipborne DRM-Based Passive Radar via Carrier Domain STAP

Remote Sensing
This paper proposes a new carrier domain approach to suppress spreading first-order sea clutter in shipborne passive radar systems using Digital Radio Mondiale (DRM) signals as illuminators.

Two Closely Related Butterflies Show Pseudo‐Concordant Patterns of Geographic Differentiation in a Heterogeneous Mountain Region

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Phylogeographic pseudo‐concordance among species—coincident spatial structuring coupled with differing levels of intraspecific differentiation—has rarely been documented in heterogeneous regions. We report a clear case in two mountain butterfly species and show how the high density of spatial sampling and the integration of phenotypic and genomic ...

Delivery of Pleckstrin‐Homology Domains Suppresses PI3K/Akt Signaling and Breast Cancer Metastasis

Advanced Science, Volume 13, Issue 30, 28 May 2026.
Current therapies curb tumor growth but not metastasis. Obscurin, a giant metastasis suppressor lost in breast cancer, restrains PI3K/Akt signaling but is impractical to restore. We deploy a mini‐obscurin, comprising the obscurin‐PH‐domain, which sequesters PI3K‐p85, potently suppressing invasion and metastasis.

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 ...

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 ...
