FMCW lidar for multiple-target sounding

SPIE Proceedings, 2010
Continuous-Wave lidars are constantly evolving in order to achieve the best performances with low power and low cost. Frequency-modulated continuous-wave (FMCW) lidar is a well-known type of lidar used for solid-target detection and ranging with high spatial resolution.

Characterizing trade‐wind shallow convection regimes in the open sea with a synergy of ship‐based vertical profiling observations

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 774, January 2026 Part A.
We use active remote sensing from a ship during the EUREC4$$ {\mathrm{EUREC}}^4 $$A campaign to characterize the environment before, during, and after precipitation in shallow convection. (1) Shallow clouds barely precipitate (only virga). Congestus clouds generate precipitation, occurring less often in the afternoon but with higher cloud fractions. (2)

MilliSonic: Pushing the Limits of Acoustic Motion Tracking

, 2019
Recent years have seen interest in device tracking and localization using acoustic signals. State-of-the-art acoustic motion tracking systems however do not achieve millimeter accuracy and require large separation between microphones and speakers, and as

FMCW RADAR SYSTEM FOR TRANSPONDER IDENTIFICATION

Progress In Electromagnetics Research B, 2018
—In this paper, we deal with a frequency modulated continuous wave (FMCW) radar used for localizing and tracking targets by frequency evaluation of the received radar beat signal. The radar system achieved with a primary radar (reader) and a secondary radar (transponder) is addressed as super high frequency (SHF) radio frequency identification (RFID ...

Computationally Efficient Pruning Before Training Scheme for SNN‐Based Radar Gesture Recognition

Electronics Letters, Volume 62, Issue 1, January/December 2026.
In this work, we propose a Spike Timing‐driven Pruning before Training (ST‐PBT) method for radar‐based human gesture recognition. The proposed ST‐PBT performs a single‐shot pruning at the model initialisation, avoiding the expensive computational cost and compression time incurred in the model pre‐training. Furthermore, the ST‐PBT introduces a gradient‐

Joint MobileViT and Knowledge Distillation Network for Hand Gesture Recognition via mmWave Radar

IET Signal Processing, Volume 2026, Issue 1, 2026.
Hand gesture recognition using mmWave radar has emerged as a promising technology for human–computer interaction (HCI), smart home systems, and the Internet of Things (IoT). However, the practical application of this technology is often constrained by the high computational complexity and significant storage demands of contemporary deep neural networks,

Radar-on-Lidar: metric radar localization on prior lidar maps

, 2020
Radar and lidar, provided by two different range sensors, each has pros and cons of various perception tasks on mobile robots or autonomous driving. In this paper, a Monte Carlo system is used to localize the robot with a rotating radar sensor on 2D ...
