A Noncontact Breathing Disorder Recognition System Using 2.4-GHz Digital-IF Doppler Radar
IEEE journal of biomedical and health informatics, 2019In this paper, a noncontact breathing disorder recognition system has been proposed for identifying irregular breathing patterns. The proposed system consists of a Doppler radar-based sensor module and a machine-learning-based breathing disorder ...

Computation of the entire clutter spectrum for Doppler radar has been reduced to a few simple formulas, by integration of reflected energy between constant Doppler loci, using the fourth power range law. The results are widely applicable, and have been found in agreement with both flight tests and a computer program study.

Miniaturized Circularly Polarized Doppler Radar for Human Vital Sign Detection
IEEE Transactions on Antennas and Propagation, 2019In this paper, a miniaturized circularly polarized (CP) continuous wave Doppler radar system operating at 2.4 GHz is presented. The radar front end consists of one left-handed CP (LHCP) antenna and one right-handed CP (RHCP) antenna, which share a single

Noncontact Sleep Stage Estimation Using a CW Doppler Radar
IEEE Journal on Emerging and Selected Topics in Circuits and Systems, 2018Sleep stage estimation is crucial to the evaluation of sleep quality and is a proven biometric in diagnosing cardiovascular diseases. In this paper, we design a continuous wave (CW) Doppler radar to accurately measure sleep-related signals, including ...
