Omnidirectional Motion Classification With Monostatic Radar System Using Micro-Doppler Signatures
IEEE Transactions on Geoscience and Remote Sensing, 2020In remote sensing, micro-Doppler signatures are widely used in moving target detection and automatic target recognition. However, since Doppler signatures are easily affected by the moving direction of the target, prior information of aspect angle is ...

A Doppler radar is defined by as 'a radar which uses the Doppler effect to determine the radial component of relative radar target velocity or to select targets having particular radial velocities.' A pulse-Doppler (or pulsed-Doppler) (PD) radar is defined as 'a Doppler radar that uses pulsed transmissions.' PD radar is used extensively for detecting ...

Phase-Based Methods for Heart Rate Detection Using UWB Impulse Doppler Radar
IEEE transactions on microwave theory and techniques, 2016Ultra-wideband (UWB) pulse Doppler radars can be used for noncontact vital signs monitoring of more than one subject. However, their detected signals typically have low signal-to-noise ratio (SNR) causing significant heart rate (HR) detection errors, as ...

Multistatic micro-doppler radar for determining target orientation and activity classification
IEEE Transactions on Aerospace and Electronic Systems, 2016Micro-Doppler radar signals can be used to separate moving human targets from stationary clutter and also to identify and classify human movements. Traditional micro-Doppler radar, which uses a single-sensor, monostatic system, suffers from the drawback ...

Doppler Radar Observations of Mammatus
Monthly Weather Review, 1995Abstract Observations of mammatus-like cloud features associated with a convective rain shower were obtained using a vertically pointing 8-mm-wavelength Doppler radar. The radar's excellent sensitivity and resolution allowed even very weak, finescale features of the cloud to be resolved.
