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

open access: yesRemote 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 ...

Comparison of the performance of adaptive space-time processing against the background of alternative methods [PDF]

open access: yesBiuletyn Wojskowej Akademii Technicznej, 2020
Description and successive stages of the STAP algorithm were characterized in this article. The ability to detect an object by using 6-element antenna array without space-time processing and using the STAP technique were compared and shown.

Random Matrix Theory-Based Reduced-Dimension Space-Time Adaptive Processing under Finite Training Samples

open access: yesRemote Sensing, 2022
Space-time adaptive processing (STAP) is a fundamental topic in airborne radar applications due to its clutter suppression ability. Reduced-dimension (RD)-STAP can release the requirement of the number of training samples and reduce the computational ...

Space-Time Adaptive Processing by Employing Structure-Aware Two-Level Block Sparsity

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Traditional radar space-time adaptive processing (STAP) cannot efficiently suppress heterogeneous clutter because of a small number of independent and identically distributed training snapshots.

The Functional Properties and Physiological Roles of Signal-Transducing Adaptor Protein-2 in the Pathogenesis of Inflammatory and Immune Disorders

open access: yesBiomedicines, 2022
Adaptor molecules play a crucial role in signal transduction in immune cells. Several adaptor molecules, such as the linker for the activation of T cells (LAT) and SH2 domain-containing leukocyte protein of 76 kDa (SLP-76), are essential for T cell ...

Signal-transducing adaptor protein-2 modulates T-cell functions

open access: yesExploration of Immunology, 2022
Immune responses are orchestrated by controlling the initiation, magnitude, and duration of various signaling pathways. Adaptor proteins act as positive or negative regulators by targeting critical molecules of signaling cascades.

Multi-Resolution STAP for Enhanced Ultra-Low-Altitude Target Detection

open access: yesRemote Sensing, 2021
In this paper, an ultra-low-altitude target (ULAT) detection approach, referred to as the multi-resolution space-time adaptive processing (STAP), is proposed to enhance the target detection performance in a missile-borne radar system.
