N2 - Radar-based human tracking can be applied to indoor healthcare scenarios, such as fall detection of elderly people. In this work, a portable frequency-modulated continuous-wave (FMCW) radar prototype for indoor human tracking is presented. The system provides absolute-range detection capabilities. Furthermore, it uses a novel approach-not requiring the sharing of the generation and acquisition clocks-to possess the highly-desired coherence feature, which enables the preservation of the phase history of targets. As a result, videos of inverse synthetic aperture radar (ISAR) images-i.e., videos of range-Doppler frames-can be reconstructed. Experimental results for a walking person in a highly-cluttered indoor environment confirm the suitability of the low-cost radar prototype for indoor healthcare applications.
