A model for gravity-wave spectra observed by Doppler sounding systems [PDF]
, 1986 A model for Mesosphere - Stratosphere - Troposphere (MST) radar spectra is developed following the formalism presented by Pinkel (1981). Expressions for the one-dimensional spectra of radial velocity versus frequency and versus radial wave number are ...

Sensors, 2018 Different from microwave radar, laser radar could be more sensitive to the micro-Doppler (m-D) effect due to its wave length. This limits the application of conventional methods, such as time–frequency based approach, since the processing needs a ...

Discrete radar based on modulo arithmetic
EURASIP Journal on Advances in Signal ProcessingZak-OTFS is a modulation scheme where signals are formed in the delay–Doppler (DD) domain, converted to the time domain (DD) for transmission and reception, then returned to the DD domain for processing.

IEEE Access, 2016 We investigate the feasibility of estimating the total energy expenditure (TEE) of a human for walking/running activities with micro-Doppler signatures. Doppler radar can capture micro-Doppler signatures produced from limb motions when a human moves.

Identification of Parametric Underspread Linear Systems and Super-Resolution Radar
, 2010 Identification of time-varying linear systems, which introduce both time-shifts (delays) and frequency-shifts (Doppler-shifts), is a central task in many engineering applications.

Passive Radar for Opportunistic Monitoring in E-Health Applications
IEEE Journal of Translational Engineering in Health and Medicine, 2018 This paper proposes a passive Doppler radar as a non-contact sensing method to capture human body movements, recognize respiration, and physical activities in e-Health applications.
