Joint Vector Sensor Beam Steering and Passive Time Reversal for Underwater Acoustic Communications
IEEE Access, 2022 This paper investigates how to advantageously combine acoustic vector sensor field components for underwater communications. The joint vector sensor beam steering and passive time-reversal receiver structure is proposed and compared against beam steering

Journal of Marine Science and Engineering, 2019 Capon beamforming is often applied in passive sonar to improve the detectability of weak underwater targets. However, we often have no accurate prior information of the direction-of-arrival (DOA) of the target in the practical applications of passive ...

New convex approaches to general MVDR robust adaptive beamforming problems
Electronics Letters, 2023 Consider general minimum variance distortionless response (MVDR) robust adaptive beamforming problems based on the optimal estimation for both the desired signal steering vector and the interference‐plus‐noise covariance (INC) matrix.

A recursive Bayesian beamforming for steering vector uncertainties [PDF]
EURASIP Journal on Advances in Signal Processing, 2013 A recursive Bayesian approach to narrowband beamforming for an uncertain steering vector of interest signal is presented. In this paper, the interference-plus-noise covariance matrix and signal power are assumed to be known. The steering vector is modeled as a complex Gaussian random vector that characterizes the level of steering vector uncertainty ...

Trajectory entrainment with human assistance of wheeled mobile system
Nihon Kikai Gakkai ronbunshu, 2020 Cart control requires propulsion and steering simultaneously. It will impose the user a hard workload in crowded environment. To overcome this problem, we design a safe auto-steering wheeled mobile system.

A Robust STAP Method Based on Alternating Projection and Clutter Cancellation
IEEE Access, 2019 Space-time steering vector mismatch of targets usually happens in the space-time adaptive processing (STAP) technique, causing space-time beam distortion. Due to the effects of clutter spectrum broadening and jamming, performance of the conventional STAP
