Doppler Radar Observations of a Hailstorm [PDF]

open access: yesJournal of Applied Meteorology, 1975
Abstract A severe hailstorm, occuring on 10 August 1966, passed over a zenith pointing, X-band, pulsed-Doppler radar located on a mountain in southeastern Arizona. An analysis was made of measurements of radar reflectivity, mean Doppler velocity, variance of the Doppler spectrum, and calculated updraft velocity.

Space-Range-Doppler Focus-Based Low-observable Moving Target Detection Using Frequency Diverse Array MIMO Radar

open access: yesIEEE Access, 2018
The radar echoes of moving targets in a clutter background are extremely weak and their characteristics are complex. A low-observable moving target detection technology has become a key constraint to radar performance, requiring the radar to provide ...

A study of the 23 October 2022 southern England damaging MCS

open access: yesWeather, Volume 80, Issue 10, Page 324-334, October 2025.
During the afternoon of 23 October 2022, a mesoscale convective system (MCS) developed and intensified over the English Channel and tracked north‐northeastward into southern England, producing widespread damaging winds and at least three moderate to strong tornadoes in Hampshire.

Planetary radar [PDF]

open access: yes
The radar astronomy activities supported by the Deep Space Network are reported. The high power S- and X-band radar transmitters at the Goldstone 64 meter station were used for a radar probe of Mars during January, February, and March 1980, which was ...

Survey and Modeling of Windblown Ejecta Deposits on Venus

open access: yesAGU Advances, Volume 6, Issue 5, October 2025.
Abstract Venus' thick atmosphere rotates in the same direction as the solid body, but ∼60 times faster. This atmospheric superrotation has produced dozens of windblown ejecta deposits (“parabolas”) on the surface of Venus. The formation and modification of parabolas is an interplay between impacts, aeolian modification, and atmospheric dynamics.

Radar principles [PDF]

open access: yes
Discussed here is a kind of radar called atmospheric radar, which has as its target clear air echoes from the earth's atmosphere produced by fluctuations of the atmospheric index of refraction.

Chung-Li, Taiwan dual mode (Doppler and spaced antenna) VHF radar: Preliminary specifications [PDF]

open access: yes, 1983
A major unresolved question in the field of atmospheric research using VHF radar techniques is the relative merit of the two most widely used systems. These systems are the Doppler method and the spaced antenna method.
