Radar Stride Rate Extraction

Abstract

We seek to understand the extraction of radar signals generated by human motion and extract information from them. We demonstrate the extraction of information associated with gait, especially the stride rate, from radar data. We describe algorithms used for detection, the radar sensors used for the measurements, and detail some of the features that can be extracted. We make measurements of human subjects in outdoor clutter backgrounds for identification. These features can serve as identifying information in a scene with multiple subjects. We gather ground truth using video and accelerometers to validate the radar data.
