Minimum redundancy MIMO radars [PDF]
2008 IEEE International Symposium on Circuits and Systems (ISCAS), 2008 The multiple-input multiple-output (MIMO) radar concept has drawn considerable attention recently. In the traditional single-input multiple-output (SIMO) radar system, the transmitter emits scaled versions of a single waveform. However, in the MIMO radar system, the transmitter transmits independent waveforms.

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

Antipode, Volume 58, Issue 2, 2026.Abstract The paper examines the existing relationships between universities and Frontex, investigating and problematising the intersection between the higher education sector and the violence of the European border regime. We introduce the concept of positivist dissonance to conceptualise these relationships within the wider “industrial‐military ...

IET Communications, Volume 20, Issue 1, January/December 2026.This research proposes a Regularised Hyperparameter Bilevel Optimisation with Continual Learning‐based Deep Neural Network (RHBO‐CLDNN) for beamforming in an Ultra‐Wide Band (UWB) system. The RHBO ensures the hyperparameter efficiency at both upper and lower levels, which allows DNN to fine‐tune the unique characteristics of the UWB system, which leads

Network MIMO with Partial Cooperation between Radar and Cellular Systems
, 2015 To meet the growing spectrum demands, future cellular systems are expected to share the spectrum of other services such as radar. In this paper, we consider a network multiple-input multiple-output (MIMO) with partial cooperation model where radar ...

UAV‐Radar‐Based Through‐Wall Human Activity Recognition via Frequency‐Selective STFT‐ResNet
Electronics Letters, Volume 62, Issue 1, January/December 2026.This letter presents a UAV‐mounted radar system for through‐wall human activity recognition in high‐rise buildings. By combining STFT‐based spectrogram processing with a frequency‐selective ResNet18 network, the method effectively filters noisy subcarriers and classifies activities with high accuracy. Experimental results demonstrate 98.08% recognition
