Doppler-based detection and tracking of humans in indoor environments

In this paper, the principles of Doppler processing to detect and track human movers in indoor environments are presented. The topics discussed include the micro-Doppler characteristics of humans, the azimuth, elevation and range tracking of humans using Doppler, spatial and frequency diversity, the effect of walls, and the characteristics of dynamic clutters from non-humans. The studies are supported by simulation and measurement results.
