Micro‐Doppler signals refer to Doppler scattering returns produced by the motions of the
target other than gross translation. The small micro‐motions of a subject, and even just parts …

Target motions, other than the main bulk translation of the target, induce Doppler
modulations around the main Doppler shift that form what is commonly called a target micro …

In this paper, a sparsity-driven method of micro-Doppler analysis is proposed for dynamic
hand gesture recognition with radar sensors. First, sparse representations of the echoes …

The potential for using micro‐Doppler signatures as a basis for distinguishing between
aided and unaided gaits is considered in this study for the purpose of characterising normal …

In this paper, a novel feature extraction technique for micro-Doppler classification and its
real-time implementation using a support vector machine classifier on a low-cost, embedded …

Phase modulation induced by target micromotions introduces sidebands in the radar
spectral signature returns. Time-frequency distributions facilitate the representation of such …

Safety and security applications benefit from better situational awareness. Radar micro‐
Doppler signatures from an observed target carry information about the target's activity, and …

In this study, a feature extraction algorithm is presented which automatically generates a set
of shape spectrum features based on the cadence velocity diagram of the human micro …

Human activity detection outdoors is emerging as a very important research field due to its
potential application in surveillance, assisted living, search and rescue, and military …

This paper presents a detection method of remotely identifying a potential active shooter
with a concealed rifle/shotgun based on radar micro-Doppler and range-Doppler signature …
