Sparse Detection Algorithms Based on Two-Dimensional Compressive Sensing for Sub-Nyquist Pulse Doppler Radar Systems

IEEE Access, 2019
Sub-Nyquist pulse Doppler radar system has received wide attention recently because it can make the sampling rate lower than the Nyquist sampling rate. However, there are still two problems that must be addressed for sub-Nyquist pulse Doppler radar.

Micro-Doppler Ambiguity Resolution Based on Short-Time Compressed Sensing

Journal of Electrical and Computer Engineering, 2015
When using a long range radar (LRR) to track a target with micromotion, the micro-Doppler embodied in the radar echoes may suffer from ambiguity problem.

Horseshoe‐Shaped Vortices Accompanied With Breaking of Upward Propagating Gravity Waves and Their Relation to Mean‐Flow Acceleration

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 24, 28 December 2025.
Abstract Breaking gravity waves (GWs) are a major source of turbulence and momentum deposition in the middle atmosphere. In spite of the importance of this phenomenon, the small‐scale vortex structures associated with wave breaking remain poorly documented under realistic conditions.

Dynamic Doppler Characteristics of Maritime Airborne Corner Reflector

Journal of Marine Science and Engineering
The maritime airborne corner reflector (ACR) is a radar reflector that can measure wind speed in an unknown sea area in real time over a long distance. To improve our understanding of how the ACR works, we investigated the Doppler characteristics of the ...

Improving range resolution with a frequency-hopping technique [PDF]

Range resolution of a conventional pulsed Doppler radar is determined by the scattering volume defined by the transmitted pulse shape. To increase the resolution, the length of the pulse must be reduced.
