Portable Radar for Noncontact Heart Rate Monitoring and Estrus Detection in Dairy Cows

open access: yesIEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
This study introduces a portable radar system for real‐time monitoring of respiratory and heart rates in dairy cows. It uses millimeter‐wave Frequency Modulated Continuous Wave (FMCW) radar to perform noncontact physiological sensing, reducing behavioral disturbance. The radar system's design prioritizes portability, cost‐effectiveness, and robustness,

Classification of Interference Signal for Automotive Radar Systems With Convolutional Neural Network

open access: yesIEEE Access, 2020
When a radar signal generated by another vehicle arrives at an ego-vehicle, mutual interference occurs, which can seriously degrade the detection performance of the radar.

Detailed Analysis and Modeling of Phase Noise and Systematic Phase Distortions in FMCW Radar Systems

open access: yesIEEE Journal of Microwaves, 2022
In coherent continuous-wave (CW) radar systems, such as frequency-modulated CW (FMCW) radar systems, measurement precision is distorted by phase noise and systematic phase errors during radar signal generation.

First Triple‐Frequency Retrievals of Binned Raindrop Size Distributions

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Our understanding of raindrop size distributions (DSDs) aloft is largely limited, owing to a scarcity of effective measurements. In this study, a two‐step optimal estimation technique is developed for retrieving binned DSDs based on a newly developed vertically‐pointing triple‐frequency radar system. In the first step, we employ the Tridon and

Proposal of multiple access FMCW radar for inter-radar interference avoidance

open access: yesThe Journal of Engineering, 2019
Inter-radar interference will be a crucial problem when a number of frequency modulated continuous wave (FMCW) radars are densely deployed in future, since it can cause miss detection and false detection of the target due to wideband interference and ...

Modeling FMCW Radar for Subsurface Analysis

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
Determining subsurface properties through ground penetrating radar sounding can be challenging, especially in planetary exploration, where little is known about the terrain and additional observations are limited. Analysis and interpretation of data acquired with the Radar Imager for Mars’ Subsurface Experiment (RIMFAX) could therefore be ...

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

open access: yesQuarterly 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)

Micro-Doppler Based Human-Robot Classification Using Ensemble and Deep Learning Approaches

open access: yes, 2018
Radar sensors can be used for analyzing the induced frequency shifts due to micro-motions in both range and velocity dimensions identified as micro-Doppler ($\boldsymbol{\mu}$-D) and micro-Range ($\boldsymbol{\mu}$-R), respectively.

Gait Analysis of Horses for Lameness Detection with Radar Sensors [PDF]

open access: yes, 2017
This paper presents the preliminary investigation of the use of radar signatures to detect and assess lameness of horses and its severity. Radar sensors in this context can provide attractive contactless sensing capabilities, as a complementary or ...
