Analysis of amplitude statistical and correlation characteristics of high grazing angle sea-clutter
The Journal of Engineering, 2019 Research on the characteristics of sea clutter has always been the focus in the problem of sea target detection as an indispensable part. In recent years, the problem of sea clutter characteristics under medium-high grazing angle is also paid more and ...

Advanced Robotics Research, EarlyView.A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Single snapshot coherent detection in sea clutter [PDF]
, 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

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.
