Small Floating Target Detection Method Based on Chaotic Long Short-Term Memory Network
Journal of Marine Science and Engineering, 2021 In order for the detection ability of floating small targets in sea clutter to be improved, on the basis of the complete ensemble empirical mode decomposition (CEEMD) algorithm, the high-frequency parts and low-frequency parts are determined by the ...

Multichannel analysis and suppression of sea clutter for airborne microwave radar systems
, 2022 S.2385-2399One efficient method to detect slow targets with low signal-to-clutter-plus-noise ratios is space time adaptive processing (STAP). To apply STAP to maritime radar systems, the multichannel properties of sea clutter have to be known. This paper

Model Predictive Control for Magnetically Actuated Cellbots
Advanced Robotics Research, EarlyView.Magnetically actuated cellbots, formed by embedding microrobots in living cells, are steered along precise paths using a model predictive controller enhanced with a Gaussian process disturbance estimator. The data‐efficient method calibrates each cellbot individually, cutting modeling error by roughly 60% and enabling accurate navigation through cell ...

Single snapshot coherent detection in sea clutter
, 2019 In this paper we consider the problem of coherent target detection in sea clutter. This is a challenging problem where traditional detectors exhibit significant performance degradation due to the non-Gaussianity and inhomogeneity of the radar returns. To
