Experimental Research on Micro-Doppler Effect of Multi-rotor Drone with Digital Television Based Passive Radar

Leida xuebao, 2018
In this paper, experimental results of micro-Doppler effect on a multi-rotor drone with digital television based passive radar are discussed. First, the bistatic passive radar micro-motion model of the drone is established.

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.

Characterizing Greater Houston's Aerosol by Air Mass During TRACER

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 14, 28 July 2025.
Abstract During the TRacking Aerosol and Convection interaction ExpeRiment (TRACER), a suite of aerosol and cloud measurements were made using the Texas A&M Rapid Onsite Atmospheric Measurement Van (ROAM‐V) mobile instrument platform. Joint ROAM‐V/radiosonde deployments focused on sampling polluted marine and continental air masses to understand ...

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

IEEE 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 ...

Direct Observation of Quasi‐Monochromatic Gravity Wave Packets Associated With the Polar Night Jet Using a Doppler‐Rayleigh Lidar

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 14, 28 July 2025.
Abstract An advanced hodograph technique was applied to extract quasi‐monochromatic, linear gravity wave (GW) packets from simultaneous wind and temperature measurements made using a ground‐based Doppler‐Rayleigh‐Mie‐Raman lidar located in Kühlungsborn (54°N, 12°E).

Design of Dual-Mode Local Oscillators Using CMOS Technology for Motion Detection Sensors

Sensors, 2018
Recently, studies have been actively carried out to implement motion detecting sensors by applying radar techniques. Doppler radar or frequency-modulated continuous wave (FMCW) radar are mainly used, but each type has drawbacks.

Direct Ocean Tidal Current Measurements From Space: Enhanced Interpretation of Sentinel‐1 Doppler Shift Signals

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Advances in Sentinel‐1 Doppler processing have continued to unlock deeper understanding of surface current dynamics. With future missions emphasizing total surface currents observations, the resolving of processes will grow, including tidal currents.
