Measurement and analysis of human micro-Doppler features in foliaged environments

The focus of this work is on measuring and classifying human micro-Doppler features in forested environments. As a first step, measurements of human motion activities are performed in an open space environment to establish the baseline of this study. Next, forest measurements were taken at two locations in a local park for: different frequencies, activities, and number of subjects. Each experimental trial was measured for 20 seconds using a vector network analyzer (VNA) and post-processed into spectrograms, from which features are extracted to classify human motion activities.
