Forensic Application of FM-CW and Pulse Radar [PDF]

Journal of Environmental & Engineering Geophysics, 2003
Ground-penetrating radar (GPR) technology has supplied vital assistance in criminal investigations. However, law enforcement personnel desire further developments such that the technology is rapidly deployable, and that it provides both a simple user interface and sophisticated target identification.

MIMO noise radar - matched filters and coarrays [PDF]

, 2008
Copyright © 2008 IEEEThe noise radar concept can be extended to an array of K transmit antenna and M receive antenna. When independent noise sources are transmitted from each antenna the approach may be viewed as a special case of MIMO radar and matched ...

Guideline Concordance of ChatGPT‐Generated Responses on Antibiotic Prophylaxis in Endodontics

Journal of Dental Education, EarlyView.
ABSTRACT Antibiotic prophylaxis decision‐making in endodontics represents a core competency in dental education, requiring the integration of systemic risk assessment, guideline interpretation, and antimicrobial stewardship principles. Although artificial intelligence (AI) tools such as ChatGPT are increasingly accessed by students and clinicians for ...

Micro-motion feature extraction of space targets based on sinusoidal frequency modulation Fourier transform

The Journal of Engineering, 2019
The space target can be discriminated from other objects by the micro-motion feature difference. The micro-motion features of a space target with precession include the spinning period, the precession angle and the precession period etc. The main work of

The radar signature of the Wind Lens: a less disruptive wind turbine? [PDF]

, 2012
We study the radar signature of a new type of wind turbine, named the Wind Lens. This design includes a flanged shroud around the turbine which concentrates the wind flow past the turbine blades and hence improves the efficiency.

Intercomparison of a Regional Climate Model Ensemble for Selected European Catchments

International Journal of Climatology, EarlyView.
This study analyzes a regional climate model ensemble for water cycle and water resource research with two models. Results show that ICON generally outperforms TSMP1 simulations, mainly with 2‐m temperature and precipitation. These findings serve as a baseline evaluation that shows how key structural differences influence the model skill.

Ground clutter simulation for airborne forward-looking multi-channel LFMCW radar

The Journal of Engineering, 2019
Ground clutter is a crucial factor that affects the detection performance of the airborne forward-looking multi-channel linear frequency modulated continuous wave (LFMCW) radar, so the distribution characteristics of studying the ground clutter plays an ...

Newtonalized orthogonal matching pursuit for the linear frequency‐modulated pulse frequency agile radar

IET Radar, Sonar & Navigation, 2021
The linear frequency‐modulated frequency agile radar (FAR) can be used for synthesizing high‐range‐resolution profiles (HRRP), and also has excellent electronic counter‐countermeasures performance. Similar to the Newtonalized orthogonal matching pursuit (
