Horizontal Divergence and Vertical Velocity Retrievals from Doppler Radar and Wind Profiler Observations

Journal of Atmospheric and Oceanic Technology, 1996
Abstract Vertical motion profiles can be diagnosed with the mass continuity equation using horizontal divergence fields derived from various single-Doppler radar techniques such as EVAD (extended velocity-azimuth display), CEVAD (concurrent extended velocity-azimuth display), and VVP (volume velocity processing).

Amplitude Barycenter Calibration of Delay-Doppler Spectrum for OTFS Signal—An Endeavor to Integrated Sensing and Communication Waveform Design

IEEE Transactions on Wireless Communications
Orthogonal time frequency space (OTFS) is considered a promising modulation technology for integrated sensing and communication (ISAC) systems, which is robust against Doppler effects in time-frequency doubly-selective channels.

FMCW-LIO: A Doppler LiDAR-Inertial Odometry

IEEE Robotics and Automation Letters
Conventional LiDAR-inertial odometry (LIO) or SLAM methods heavily rely on geometric features of environments, as LiDARs primarily provide range measurements instead of motion measurements.

Retrieval of Model Initial Fields from Single-Doppler Observations of a Supercell Thunderstorm. Part I: Single-Doppler Velocity Retrieval

Monthly Weather Review, 2002
In this two-part study, a single-Doppler parameter retrieval technique is developed and applied to a real-data case to provide initial conditions for a short-range prediction of a supercell thunderstorm. The technique consists of the sequential application of a single-Doppler velocity retrieval (SDVR), followed by a variational velocity adjustment, a ...
