Velocity Dealiased Spectral Estimators of Range Migrating Targets using a Single Low-PRF Wideband Waveform [PDF]

open access: yes, 2013
Wideband radars are promising systems that may provide numerous advantages, like simultaneous detection of slow and fast moving targets, high range-velocity resolution classification, and electronic countermeasures.

Architected Spatially Deterministic Multiscale Phase Segregation in Block Copolymer Composites for Augmented Radiative Cooling

open access: yesAdvanced Science, EarlyView.
Multiscale phase segregation in block copolymers enables spatially deterministic structuring from molecular to macroscopic scales, decoupling solar scattering and infrared emission for augmented radiative cooling. ABSTRACT Passive radiative cooling, which reflects solar irradiation while emitting heat through the atmospheric window, provides a ...

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 ...

Space scanning FMCW-based two-dimensional frequency diverse array radar

open access: yesThe Journal of Engineering, 2019
The frequency-modulated continuous wave (FMCW)-based frequency diverse array (FDA) radar concept is extended to two dimensions (2D). The radar operates as a linear pulsed FMCW/FDA in the transmission (TX) mode while it operates as a pulsed FMCW/phased ...

Effectiveness of Sustainability Rating Scales in Dual‐Labeling: The Role of Eco‐Label Familiarity in Consumer Responses

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Eco‐labels and sustainability rating scales are widely used to communicate product sustainability, yet it remains unclear whether combining these signals enhances or undermines consumer responses. Drawing on signaling theory, this study examines how eco‐label familiarity and the presence of a sustainability rating scale jointly shape consumer ...

A Flexible K‐Band FMCW Radar Prototype for Low‐RCS Nano‐Drone Detection

open access: yesIET Radar, Sonar & Navigation
Nano‐drones are insect‐like drones used to provide intelligence through their capability of intrusion and ability to carry small sensors. They pose a defence and security threat and can potentially violate secure establishments and privacy rights.

Cooperative radar with signature method for unambiguity [PDF]

open access: yesAdvances in Radio Science, 2019
The increasing availability of off-the-shelf high-frequency components makes radar measurement become popular in mainstream industrial applications. We present a cooperative FM radar for strongly reflective environments, being devised for a range of up ...

Why Some Firms Perceive Climate Risks and Others Do Not—Evidence From the Logistics Sector

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study explores how companies perceive risks stemming from climate change as a gradual process, focusing on the logistics sector. It advances research on organizational climate risk perception by integrating perspectives on embeddedness and resource configurations. Based on 41 semi‐structured interviews with representatives of 22 logistics

Caging Polyhalide Anions in Polycyclodextrin for Long‐Lasting Aqueous Zinc‐Iodine Batteries

open access: yesAngewandte Chemie, Volume 138, Issue 41, 5 October 2026.
We demonstrated poly(β‐cyclodextrin) gel as an ideal host material that effectively contains and releases polyhalide anions in aqueous zinc‐iodine batteries. Such a unique host‐guest chemistry prevents the shuttle effect of polyhalides. The corresponding batteries can operate via both 2e and 4e storage, attaining 60,000 cycles with more than 99% and 85%

Investigation on reason of range profile distortion of plasma sheath target

open access: yesThe Journal of Engineering, 2019
The range profile of the plasma sheath target is always found to be distorted when using the linear frequency modulation signal as the radar detection signal. As a result, the detection and tracking of the target became hard, or even failure. Here, three
