Sequential Separation of Radar Target Micro-Motions Based on IRT

IEEE Transactions on Aerospace and Electronic Systems, 2013
A micro-motion sequential separation method based on inverse Radon transform (IRT) is proposed. The method has an accumulation effect and, therefore can adapt to environment with relatively low signal-to-noise ratio (SNR). This method has the capability of antidiscontinuous tracking and thus is suitable in the multi-target tracking scenario. The method

Workspace investigation of a 3 DOF compliant micro-motion stage

ICARCV 2004 8th Control, Automation, Robotics and Vision Conference, 2004., 2005
This paper investigates the workspace of a three degree-of-freedom (DOF) compliant micro-motion stage with flexure hinges. This micro-motion stage has parallel structure for better stiffness and accuracy than serial structures and is driven by three PZT stack actuators.

Optimal use of nonlinear electromagnetic force for micro motion wrist

Proceedings. 1991 IEEE International Conference on Robotics and Automation, 2002
A force-sensitive multi-DOF (degree-of-freedom) wrist suitable for force and collision control is presented. Similar kinds of wrists have been developed before but they suffered from insufficiency of power or massiveness. Having practical applications in mind, the authors present a magnetically driven system in which the nonlinear and limited ...

Position control of a 3 DOF compliant micro-motion stage

ICARCV 2004 8th Control, Automation, Robotics and Vision Conference, 2004., 2005
This paper focuses on the open-loop and closed-loop position control of a three degree-of-freedom (DOF) compliant micro-motion stage with flexure hinges. This micro-motion stage has a parallel structure for better stiffness and accuracy than serial structures and is driven by three PZT stack actuators.

Human Gait Classification Using Micro-Motion and Ensemble Learning

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
In this paper, we proposed a method of human-gait classification based on a multi-gait feature and multi-classifier integration. Compared with the identity authentication by single-gait of one person, our approach can better recognize different person with multi-gait.

Micro-Doppler signatures for sensing micro-motion

2019
The micro-Doppler signature is a distinctive characteristic of micro-motion represented by intricate time-varying Doppler frequency modulations. It can be used to extract motion kinematic features for identifying an object of interest. In this Chapter, we introduce the micro-Doppler signature in radar and its applications for sensing micro-motion.

Micro-Doppler simulator of bulk and micro motions for vehicle drivers

2016 International Conference on Information and Communication Technology Convergence (ICTC), 2016
The driver's motion while driving is one of the important information that can measure the current state of the driver that is driver's attention, health, etc. In general, the driver does various additional activities in addition to driving operation. For example, operations such as audio or sun visor control, and even mobile phone in a moving vehicle ...

Design and analysis of a micro-motion manipulator

2008
The work in this report aims to design a monolithic compliant micro manipulator that is able to provide spatial motions. The kinematics of the spatial compliant manipulator is analyzed using the pseudo rigid body model (PRBM) concept. An approximate kinematic analysis method based on Constant-Jacobian is also studied.
