Distribution and size of elements of Saturn's rings as inferred from 12-cm radar observations [PDF]
A 64m radar antenna was used to observe Saturn's rings at 12.6 cm wavelength, with reduced Doppler spread. The results show a positive radar return corresponding to about a 60 percent return from an isotropic scatterer with the projected area of the ...

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The Weather Surveillance Radar–1988 Dopplers (WSR‐88Ds) are an operational network of S‐band, dual‐polarization radars in the United States. Currently, replacement options are being considered for the next generation of weather radars. One option is dual‐polarization phased array radar (PAR), which employs electronic beam steering to provide ...

Measurement of vertical velocity using clear-air Doppler radars [PDF]
A new clear air Doppler radar was constructed, called the Flatland radar, in very flat terrain near Champaign-Urbana, Illinois. The radar wavelength is 6.02 m.

Comparison of reflectivity and wind profiles measured on 46.8 MHz and 430 MHz at the Arecibo Observatory [PDF]
, 1986 Comparisons of troposphere and stratosphere radar experiments at ultrahigh frequency (UHF) and very high frequency (VHF) were done at the Arecibo Observatory in April 1980 with the 430 MHz and 46.8 MHz radar.

Radarize: Enhancing Radar SLAM with Generalizable Doppler-Based Odometry
Proceedings of the 22nd Annual International Conference on Mobile Systems, Applications and ServicesMillimeter-wave (mmWave) radar is increasingly being considered as an alternative to optical sensors for robotic primitives like simultaneous localization and mapping (SLAM). While mmWave radar overcomes some limitations of optical sensors, such as occlusions, poor lighting conditions, and privacy concerns, it also faces unique challenges, such as ...

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract A process‐oriented calibration framework is developed for the Simplified Higher‐Order Closure (SHOC) turbulence scheme in DOE's Simple Cloud Resolving E3SM Atmospheric Model (SCREAM). This framework leverages machine learning surrogates and observational constraints to efficiently calibrate SHOC adjustable parameters across two convective ...
