Micro-Doppler target scattering

2014 IEEE Radar Conference, 2014
Micro-Doppler radar has proven to be a valuable tool in which micro-motions are encoded into detailed target signatures that greatly aid identification. Models of such targets often have elaborate motion representations but only use a simple point scatterer representation to compute received echo strength.

Human polarimetric micro-doppler

SPIE Proceedings, 2011
Modern radars can pick up target motions other than just the principle target Doppler; they pick out the small micro-Doppler variations as well. These can be used to visually identify both the target type as well as the target activity. We model and measure some of the micro-Doppler motions that are amenable to polarimetric measurement ...

Multistatic radar micro-Doppler

2020
This chapter reviews how multistatic radar sensor networks can be utilised to sense a series of different moving targets to extract their micro-Doppler (μD) signatures and use these for classification purposes. The field of radar has advanced significantly since its inception in the early twentieth century.

Stride rate in radar micro-doppler images

2009 IEEE International Conference on Systems, Man and Cybernetics, 2009
We extract gait information from the radar micro-Doppler signals generated by human motion. We demonstrate the extraction of information associated with gait, especially the stride rate, from simulated and measured radar data. We describe micro-Doppler algorithms used for the extraction of stride rate, the radar sensors used for the measurements, and ...

Fine micro-Doppler analysis in ISAR imaging

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
In ISAR imaging, it's well known that rotating parts of a target such as wheels or rotors induce additional features in the Doppler frequency spectrum. These features are called micro-Doppler effect and appear as sidebands around the central Doppler frequency.

Micro-Doppler extraction from ISAR image

2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016
The micro-Doppler is an effective tool for target recognition. It is hard to detect micro-Doppler induced by vibration for its small value. In our system, phase-modulated stepped-frequency waveform is used. The method of matching pursuit (MP) is introduced to compensate translation.

Intraoperative Micro-Doppler in Cerebral Arteriovenous Malformations

Journal of Neurological Surgery Part A: Central European Neurosurgery, 2015
Intraoperative micro-Doppler (IOMD), intraoperative digital substraction angiography (DSA), and microscope-integrated indocyanine green angiography are methods that guide neurosurgical resection of arteriovenous malformations (AVMs) in the brain and minimize the trauma of healthy tissue.

Feature selection for classification of human micro-Doppler

2013 IEEE International Conference on Microwaves, Communications, Antennas and Electronic Systems (COMCAS 2013), 2013
Dozens of features have been proposed for the use in a variety of human micro-Doppler classification problems, such as activity classification, target identification, and arm swing detection. However, the issues of how many features are truly required, which features should be selected, and whether or how this selection will vary depending upon human ...

The STFT-Based Estimator of Micro-Doppler Parameters

IEEE Transactions on Aerospace and Electronic Systems, 2017
A two-stage technique for estimating micro-Doppler signal parameters has been proposed. In the first stage, rough parameter estimations are performed by regression of instantaneous frequency estimate obtained from the short-time Fourier transform. Afterwards, rough estimates are refined in the second stage. The proposed technique has better performance

Micro-Doppler Removal in the Radar Imaging Analysis

IEEE Transactions on Aerospace and Electronic Systems, 2013
The micro-Doppler (m-D) effect is caused by fast moving reflectors. This effect may significantly decrease the readability of the inverse synthetic aperture radar/synthetic aperture radar (ISAR/SAR) images. An L-statistics-based method for m-D effects removal is proposed.
