Enhancing SAR Aircraft Detection with CCS-Net: A Lightweight and Efficient Framework for Manned–Unmanned Teaming Reconnaissance

In contemporary manned–unmanned teaming (MUM-T) systems, the accurate detection of aircraft in Synthetic Aperture Radar (SAR) imagery is crucial for battlefield surveillance and target identification. However, challenges such as background clutter, significant scale variations, and limitations in existing feature extra...

Flow physics of progressive-curvature Coanda surfaces in transonic circulation control

Premature jet separation severely limits the control authority of transonic circulation control (CC) airfoils. This study investigates the flow physics governing Coanda jet attachment and develops a progressive-curvature Coanda surface at Ma=0.72 through shape optimization of the NASA-SC(2)-0714-CC supercritical airfoi...

Multi-Fidelity Gaussian Process Regression and Sequential Active Sampling for Surrogate Modeling: A Methodological Study with Validation on a Synthetic Radar Angle Tracking Benchmark

To address the challenge of limited evaluations of expensive high-complexity functions in surrogate modeling, this paper proposes a methodological framework that integrates multi-fidelity Gaussian process (MFGP) regression, sequential active sampling, and global sensitivity analysis, using a radar angle tracking accura...
