Micro motion study

2020
Work measurement as detailed in the previous chapter involves stopwatch time study of fairly long task cycles, and it becomes quite difficult to time individual elements less than 5 s.

Micro-Motions signatures analysis and extraction

2013 International Workshop on Microwave and Millimeter Wave Circuits and System Technology, 2013
Micro-Doppler features can be regarded as a unique signature of an object with movements which provide additional information for classification, recognition and identification of the object. The common analysis method of Micro-Motion is time-frequency transform.

Analysis of radar micro-motion model

2018 International Conference on Electronics Technology (ICET), 2018
Micro characteristics is essential for radar target recognition. Micro-motion is defined as some dynamics of a target except its main bulk translation. In general, micro-motions are modelled as the sinusoidal forms. However, micro-motions in reality should include more types of movement forms besides the sinusoidal one.

Radar Micro-motion Target Resolution

2006 CIE International Conference on Radar, 2006
Micro-motion such vibration and rotation induces unique phase modulation or Doppler modulation and offers a new way of characterizing objects. When multiple vibration/rotation targets detection and identification are considered, the echo signal is multi-component sinusoidal modulation signal.

Study on Clutter Suppression Method for Micro-motion Target

2019 IEEE 19th International Conference on Communication Technology (ICCT), 2019
In order to solve the problem of the energy loss of echo in the time-domain clutter suppression of narrow-band pulse radar, a novel method based on complex empirical mode decomposition(CEMD) for suppressing clutter, is proposed. Firstly, the model of the rotor micro-motion target in ground clutter, is established.

On the design of 6-DOF parallel micro-motion manipulators

Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems. Expanding the Societal Role of Robotics in the the Next Millennium (Cat. No.01CH37180), 2002
Parallel manipulators are characterized by symmetry, high precision and stiffness, which allow them to be the mechanisms of micromanipulators. This paper deals with the optimum design of micromanipulator mechanisms. A useful design tool space, named the physical model of the solution space, is proposed.

Performance Optimization for a 3-DOF Micro-Motion Device

Advanced Materials Research, 2011
Traditional parallel manipulators suffer from errors due to backlash, hysteresis, and vibration in the mechanical joints. In this paper, a new 3SPS+RPR spatial compliant mechanism which has three degrees of freedom (DOF) and can generate motions in a microscopic scale is proposed. It can be utilized for biomedical engineering and fiber optics industry.

Design and PID Control of Piezoelectric Micro-motion Stage

2018 IEEE International Conference on Intelligence and Safety for Robotics (ISR), 2018
At present, the size of piezoelectric micro-motion stage is relatively large, which is difficult to be applied to the MEMS. For this reason, a piezoelectric micro-motion stage based on lever amplification mechanism is proposed in this paper, and the external dimension is only $\pmb{ 57}\mathbf{mm}\times \pmb{57}\mathbf{mm}\times$ 5mm.

Marine Targets Recognition Through Micro-Motion Estimation from SAR data

IEEE International Workshop on Metrology for AeroSpace, 2020
The capability to perform Automatic Target Recognition (ATR) from SAR images has great importance for both civilian and military applications. However, this task becomes challenging when the quality and quantity of target information is not sufficient to
