Granular Mobility-Factor Analysis Framework for enriching Occupancy Sensing with Doppler Radar

Robust Doppler radar demodulation via compressed sensing

The microwave Doppler radar sensor enables a non-contact approach for measuring movement in various applications. One of the most challenging issues is radar signal demodulation because it requires accurate DC offset compensation. Existing works either require a complicated setup procedure or are sensitive to environmental changes. In this reported work, a compressed sensing based approach to e...

Harmonics Cancellation in Noncontact Microwave Doppler Radar Cardiopulmonary Sensing

This paper addresses the challenge of respiration harmonics cancellation in microwave Doppler radar cardiopulmonary sensing. A new signal processor based on adaptive noise cancellation is proposed. When the heartbeat signal is easily overwhelmed by the respiration harmonics, the traditional band-pass filters are used to separate heartbeat signal from the respiration signal, then the LMS-based m...

Wind observations with Doppler weather radar

Introduction Weather radars are commonly employed for detection and ranging of precipitation, but radars with Doppler capability can also provide detailed information on the wind associated with (severe) weather phenomena. The Royal Netherlands Meteorological Institute (KNMI) operates two identical C-band (5.6 Ghz) Doppler weather radars. One radar is located in De Bilt and the other one is loc...
