Micro-Doppler radar deception and camouflage of airborne targets. [PDF]

open access: yesSci Rep
Micro-Doppler signatures are ubiquitous in radar-based object recognition and classification, as they contain information about the internal structure of observed targets. While modern machine learning algorithms achieve unprecedented accuracy in target classification, they are susceptible to deceptive manipulation by introducing intelligent artificial

Dop‐NET: a micro‐Doppler radar data challenge [PDF]

open access: yesElectronics Letters, 2020
Radar sensors have a new growing application area of dynamic hand gesture recognition. Traditionally radar systems are considered to be very large, complex and focused on detecting targets at long ranges. With modern electronics and signal processing it is now possible to create small compact RF sensors that can sense subtle movements over short ranges.

Robustness of Deep Neural Networks for Micro-Doppler Radar Classification [PDF]

open access: yes2022 23rd International Radar Symposium (IRS), 2022
With the great capabilities of deep classifiers for radar data processing come the risks of learning dataset-specific features that do not generalize well. In this work, the robustness of two deep convolutional architectures, trained and tested on the same data, is evaluated.

Radar Measurement of Human Polarimetric Micro-Doppler [PDF]

open access: yesJournal of Electrical and Computer Engineering, 2013
We use polarimetric micro-Doppler for the detection of arm motion, especially for the classification of whether someone has their arms swinging and is thus unloaded. The arm is often bent at the elbow, providing a surface somewhat similar to a dihedral. This is distinct from the more planar surfaces of the body which allows us to isolate the signals of

A Deep-Learning Method for Radar Micro-Doppler Spectrogram Restoration [PDF]

open access: yesSensors, 2020
Radio frequency interference, which makes it difficult to produce high-quality radar spectrograms, is a major issue for micro-Doppler-based human activity recognition (HAR). In this paper, we propose a deep-learning-based method to detect and cut out the interference in spectrograms. Then, we restore the spectrograms in the cut-out region.

Application of S-Transform Random Consistency in Inverse Synthetic Aperture Imaging Laser Radar Imaging

open access: yesApplied Sciences, 2019
Under the same principle, laser radar could be more sensitive to the micro-Doppler (m-D) effect due to its wave length, as the characteristic of multi-resolution, S transform could reduce the influence of the micro-Doppler component and enhance the ...
