The dependence of radar target detectability on array weighting function [PDF]

open access: yes, 2009
Presented at the IET-Radar 2007 Conference Edinburgh 15-18 October 2007This paper describes simulation work to assess the detectability of targets by an airborne fire control radar (FCR) operating in a medium pulse repetition frequency (PRF) mode in ...

Developments in target micro-Doppler signatures analysis : radar imaging, ultrasound and through-the-wall radar [PDF]

open access: yes, 2013
Target motions, other than the main bulk translation of the target, induce Doppler modulations around the main Doppler shift that form what is commonly called a target micro-Doppler signature.

A Marine Radar Wind Sensor [PDF]

open access: yesJournal of Atmospheric and Oceanic Technology, 2006
AbstractA new method for retrieving the wind vector from radar-image sequences is presented. This method, called WiRAR, uses a marine X-band radar to analyze the backscatter of the ocean surface in space and time with respect to surface winds. Wind direction is found using wind-induced streaks, which are very well aligned with the mean surface wind ...

The Application of Artificial Intelligence in Predicting Embryo Transfer Outcome of Recurrent Implantation Failure

open access: yesFrontiers in Physiology, 2022
Background: Recurrent implantation failure (RIF) refers to that infertile patients have undergone multiple in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles and transferred multiple embryos without embryo implantation or ...

ECCM Schemes against Deception Jamming Using OFDM Radar with Low Global PAPR

open access: yesSensors, 2020
In this paper, a type of effective electronic counter-countermeasures (ECCM) technique for suppressing the high-power deception jamming using an orthogonal frequency division multiplexing (OFDM) radar is proposed.
