Doppler radar remote sensing of respiratory function. [PDF]

Front Physiol, 2023
Doppler radar remote sensing of torso kinematics can provide an indirect measure of cardiopulmonary function. Motion at the human body surface due to heart and lung activity has been successfully used to characterize such measures as respiratory rate and depth, obstructive sleep apnea, and even the identity of an individual subject.

G-Band Radar for Humidity and Cloud Remote Sensing [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2021
VIPR (vapor in-cloud profiling radar) is a tunable G-band radar designed for humidity and cloud remote sensing. VIPR uses all-solid-state components and operates in a frequency-modulated continuous-wave (FMCW) radar mode, offering a transmit power of 200–300 mW.

Hailstorms and rainstorms versus supercells—a regional analysis of convective storm types in the Alpine region

npj Climate and Atmospheric Science, 2023
The behaviour of severe thunderstorms, particularly supercells, in complex terrain is still poorly understood. Utilising 6 years of radar-, lightning- and radiosounding-based thunderstorm data in the domain of the Swiss radar network, we study different ...

Unraveling hydrometeor mixtures in polarimetric radar measurements [PDF]

Atmospheric Measurement Techniques, 2018
Radar-based hydrometeor classification typically comes down to determining the dominant type of hydrometeor populating a given radar sampling volume. In this paper we address the subsequent problem of inferring the secondary hydrometeor types present ...
