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 …

Contemporary surveillance systems mainly use video cameras as their primary sensor.
However, video cameras possess fundamental deficiencies, such as the inability to handle …

Human identification plays an important role in our daily lives. Previous studies have
successfully used characteristics such as fingerprints, irises, and facial features for identity …

This paper presents SilentKey, a new authentication framework to identify mobile device
users through ultrasonic-based lip reading. The main idea is to generate ultrasonic signals …

Radar-based human activity recognition is attracting a wide range of interest from both
industry and academia because of its through-wall ability, privacy-preserving capability, and …

Radar-based classification of human activities and gait have attracted significant attention
